Description Of The Business [Abstract]
Description Of The Business	1. DESCRIPTION OF THE BUSINESS Graybar Electric Company, Inc. (“Graybar”, “Company”, "we", "our", or "us") is a New York corporation, incorporated in 1925.  We are engaged in the distribution of electrical and communications and data networking products and are a provider of related supply chain management and logistics services.  We primarily serve customers in the construction, commercial, institutional and government ("CIG"), and industrial & utility vertical markets, with products and services that support new construction, infrastructure updates, building renovation, facility maintenance, repair and operations ("MRO"), and original equipment manufacturers ("OEM"). In our primary role as third-party wholesale distributor, we neither manufacture nor contract to manufacture the products that we sell; however, one of our subsidiaries may contract to manufacture some of its private label lighting fixtures.  Our business activity is primarily based in the United States (“U.S.”).  We also have subsidiary operations with distribution facilities in Canada and Puerto Rico.

Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Our accounting policies conform to generally accepted accounting principles in the U.S. ("GAAP”) and are applied on a consistent basis among all years presented. Significant accounting policies are described below. Principles of Consolidation The consolidated financial statements include the accounts of Graybar and our subsidiary companies.  All material intercompany balances and transactions have been eliminated.  The ownership interests that are held by owners other than the Company are in subsidiaries owned by the Company and are accounted for and reported as noncontrolling interests. Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities.  Actual results could differ from these estimates. Revenue Recognition Sales revenue is recognized when performance obligations are satisfied, which is typically upon delivery of the product to the customer.  Sometimes product is purchased from the manufacturer and drop-shipped to the customer. We generally take control of the goods when shipped by the manufacturer and then recognize revenue when control of the product transfers to the customer. Revenues recognized are primarily for product sales, but may also include freight and handling charges. Our standard warehouse shipping terms are FOB shipping point, under which control passes to the customer at the time of shipment. We also earn revenue for professional services, general contracting services, and storage services. Such service revenue represented less than 1% of net sales for the years ended December 31, 2021, 2020, and 2019.  Revenue is reported net of all taxes, primarily sales tax, assessed by governmental authorities as a result of revenue-producing transactions. Outgoing Freight Expenses We record 95% of outgoing freight expenses as a component of selling, general and administrative expenses.  Total outgoing freight expenses were $78.9 million, $68.8 million, and $68.5 million for the years ended December 31, 2021, 2020, and 2019, respectively. Cash and Cash Equivalents We account for cash on hand, deposits in banks, and other short-term, highly liquid investments with an original maturity of three months or less as cash and cash equivalents. Allowance for Credit Losses We perform ongoing credit evaluations of our customers, and a significant portion of our trade receivables is secured by mechanic’s lien or payment bond rights.  We maintain allowances to reflect the expected uncollectability of trade receivables based on past collection history pooled on the aging of the receivables, specific risks identified in the receivables portfolio based on current conditions, and expected future economic conditions when necessary.  Although actual credit losses have historically been within management’s expectations, additional allowances may be required if the financial condition of our customers were to deteriorate. Merchandise Inventory Our inventory, comprised entirely of finished goods, is stated at the lower of cost (generally determined using the last-in, first-out (“LIFO”) cost method) or market.  LIFO accounting is a method of accounting that, compared with other inventory accounting methods, generally provides better matching of current costs with current sales. We make provisions for obsolete or excess inventories as necessary to reflect reductions in inventory value. Vendor Allowances Our agreements with many of our suppliers provide for us to earn volume incentives based on purchases during the agreement period.  Based on the provisions of our vendor agreements, we develop vendor accrual rates by estimating our performance under the agreements and the amounts that will be earned. We perform analyses and review historical trends to ensure the deferred amounts earned are appropriately recorded. Certain vendor agreements contain purchase volume incentives that provide for increased funding when graduated purchase volumes are met. Amounts accrued throughout the year are based on estimates of future activity levels, and could be materially impacted if actual purchase volumes differ. Changes in the estimated amount of incentives are treated as changes in estimate and are recognized in income from operations in the period in which the change in estimate occurs.  In the event that the operating performance of our suppliers were to decline, however, there can be no assurance that amounts earned would be paid or that the volume incentives would continue to be included in future agreements. Property and Depreciation Property is recorded at cost. Depreciation is expensed on a straight-line basis over the estimated useful lives of the related assets. Interest costs incurred to finance expenditures for major long-term construction projects are capitalized as part of the asset's historical cost and included in property, then depreciated over the useful life of the asset. Leasehold improvements are amortized over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Expenditures for maintenance and repairs are charged to expense when incurred, while the costs of significant improvements, which extend the useful life of the underlying asset, are capitalized. Fair Value We endeavor to utilize the best available information in measuring fair value.  GAAP has established a fair value hierarchy, which prioritizes the inputs used in measuring fair value.  The tiers in the hierarchy include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own data inputs and assumptions.  We have used fair value measurements to value our pension plan assets. Foreign Currency Exchange Rate The functional currency for our Canadian subsidiary is the Canadian dollar.  Accordingly, its balance sheet amounts are translated at the exchange rates in effect at the end of each reporting period and its statements of income amounts are translated at the average rates of exchange prevailing during the current period.  Currency translation adjustments are included in accumulated other comprehensive loss. Goodwill Our goodwill is not amortized, but rather tested annually for impairment.  Goodwill is reviewed annually in the fourth quarter and when circumstances or other events might indicate that impairment may have occurred.  We first perform a qualitative assessment of goodwill impairment. The qualitative assessment considers several factors including the excess fair value over carrying value as of the last quantitative impairment test, the length of time since the last fair value measurement, the current carrying value, market conditions, actual performance compared to forecasted performance, and the current business outlook. If the qualitative assessment indicates that it is more likely than not that goodwill is impaired, the reporting unit is then quantitatively tested for impairment. If a quantitative assessment is required, the fair value is determined using a variety of assumptions including estimated future cash flows of the reporting unit using applicable discount rates. Definite Lived Intangible Assets The cost of intangible assets with determinable useful lives is amortized to reflect the pattern of economic benefits consumed on a straight-line basis over the estimated periods benefited. Customer relationships, trade names and other non-contractual intangible assets with determinable lives are amortized over periods generally ranging from 3 to 20 years. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired. Income Taxes We recognize deferred tax assets and liabilities to reflect the future tax consequences of events that have been recognized in the financial statements or tax returns.  A deferred tax asset or liability results from the temporary difference between an item’s carrying value as reflected in the financial statements and its tax basis, and is calculated using enacted applicable tax rates.  We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, a valuation allowance is established.  Changes in the valuation allowance, when recorded, are included in the provision for income taxes in the consolidated financial statements.  We classify interest expense and penalties as part of our provision for income taxes based upon applicable federal and state interest/underpayment percentages. We assess uncertainty regarding tax positions taken in previously filed returns and record reserves in accordance with the guidance under Accounting Standards Codification ("ASC") 740-10, "Accounting for Uncertainty in Income Taxes". Other Postretirement Benefits We account for postretirement benefits other than pension benefits by accruing the costs of benefits to be provided over the eligible employees’ periods of active service.  These costs are determined on an actuarial basis.  Our consolidated balance sheets reflect the funded status of postretirement benefits. Pension Plan We sponsor a noncontributory defined benefit pension plan accounted for by accruing the cost to provide the benefits over the eligible employees’ periods of active service.  These costs are determined on an actuarial basis.  Our consolidated balance sheets reflect the funded status of the defined benefit pension plan. Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and non-current operating lease liabilities on our consolidated balance sheets. Amounts related to finance leases are included in property, current portion of long-term debt, and long-term debt on our consolidated balance sheets. ROU assets and lease liabilities are recognized and measured on the date the underlying asset is made available to us. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. We use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. For certain leases, such as real estate and information technology (IT) equipment, we account for the lease and non-lease components as a single lease component. For all other leases, we account for the lease and non-lease components separately. We have elected as an accounting policy not to apply the recognition requirements for short-term leases. Therefore, leases with a term of twelve months or less are not recorded on the consolidated balance sheets. Lease expenses associated with short-term leases are immaterial and are recorded in the consolidated statements of income in selling, general and administrative expenses. Additionally, for certain vehicle leases, we apply a portfolio approach to account for the operating lease ROU assets and liabilities. Non-Operating Expenses Non-operating expenses are comprised of interest expense, net and non-service cost components of the net periodic benefit cost for the pension and other postretirement benefit plans. The non-service cost components include interest cost, expected return on plan assets, amortization of net actuarial gains/losses, amortization of prior service costs/gains, and charges due to settlement of certain plan liabilities. New Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU” or “Update”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” that provides temporary relief to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative rates. This Update is effective for all entities as of March 12, 2020 through December 31, 2022. The guidance on contract modifications, which is applicable to Graybar, can be applied prospectively from any date beginning March 12, 2020 and may also be applied to modifications of existing contracts made earlier in the interim period that includes March 12, 2020. We have evaluated the impact of the adoption of the Update on our contracts and our consolidated financial statements. We do not engage in hedging transactions and we have the option under our Amended Credit Agreement, as defined in Note 12, “Debt”, to continue to use LIBOR until June 30, 2023. As such, this Update does not have a material impact on our contracts and our consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”, which requires companies to apply ASC 606, “Revenue from Contracts with Customers” to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. This creates an exception to the general recognition and measurement principle in ASC 805, which uses fair value. The guidance is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption is permitted and the guidance should be applied prospectively. We are currently evaluating the impact of adopting the Update on our consolidated financial statements, and the adoption would be dependent upon whether we pursue any acquisitions in the future.

Inventory [Abstract]
Inventory	5. INVENTORY Our inventory, comprised entirely of finished goods, is stated at the lower of cost (generally determined using the LIFO cost method) or market.  Inventories valued using the LIFO method comprised 87% and 89% of the total inventories at December 31, 2021 and 2020, respectively. Had the first-in, first-out (“FIFO”) method been used, merchandise inventory would have been $427.9 million and $227.2 million greater than reported under the LIFO method at December 31, 2021 and 2020, respectively.  We did not liquidate any portion of previously-created LIFO layers in 2021 and 2019. In 2020, we liquidated portions of previously created LIFO layers, resulting in decreases in cost of merchandise sold of $4.1 million. Reserves for excess and obsolete inventories were $14.0 million and $8.6 million at December 31, 2021 and 2020, respectively.  The change in the reserve for excess and obsolete inventories, included in cost of merchandise sold, was $5.4 million, $(0.6) million, and $1.4 million for the years ended December 31, 2021, 2020, and 2019, respectively.

Property And Depreciation [Abstract]
Property and Depreciation	6. PROPERTY AND DEPRECIATION We provide for depreciation and amortization using the straight-line method over the following estimated useful asset lives: ClassificationEstimated Useful Asset LifeBuildings42 yearsLeasehold improvementsOver the shorter of the asset’s life or the lease termFurniture, fixtures, equipment and software3 to 14 yearsAssets held under finance leasesOver the shorter of the asset’s life or the lease term Depreciation expense was $36.2 million, $36.7 million, and $36.1 million in 2021, 2020, and 2019, respectively. At the time property is retired or otherwise disposed, the asset and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is credited or charged to other income, net. We consider properties to be assets held for sale when all of the following criteria are met: (i) a formal commitment to a plan to sell a property has been made and exercised; (ii) the property is available for sale in its present condition; (iii) actions required to complete the sale of the property have been initiated; (iv) sale of the property is probable and we expect the sale will occur within one year; and (v) the property is being actively marketed for sale at a price that is reasonable given its current market value. Upon designation as an asset held for sale, we record the carrying value of each property at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and depreciation of the property ceases. There were no assets held for sale at December 31, 2021 or 2020. During the year ended December 31, 2021, we sold assets classified as held for sale with a net book value of $0.4 million, and recorded a gain of $9.1 million in other income, net. During the year ended December 31, 2020, we sold assets classified as held for sale with a net book value of $4.4 million, and recorded a net gain of $3.4 million in other income, net. We did not sell any assets classified as held for sale in 2019. We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.  For assets classified as held and used, impairment may occur if projected undiscounted cash flows are not adequate to cover the carrying value of the assets.  In such cases, additional analysis is conducted to determine the amount of the loss to be recognized.  The impairment loss is calculated as the difference between the carrying amount of the asset and its estimated fair value.  The analysis requires estimates of the amount and timing of projected cash flows and, where applicable, selection of an appropriate discount rate.  Such estimates are critical in determining whether any impairment charge should be recorded and the amount of such charge if an impairment loss is deemed necessary.

Leases [Abstract]
Leases	7. LEASES We have operating and finance leases for corporate offices, warehouse buildings, sales offices, branch locations, vehicles, and certain equipment. Our leases have remaining lease terms of one to ten years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases within one year. In addition to fixed lease payments, we incur variable lease charges that are recognized as incurred. These charges are primarily for maintenance and real estate taxes on leased facilities. The components of the lease expense for the years ended December 31, 2021, 2020, and 2019 were as follows: For the Years Ended December 31, 2021 20202019Operating lease cost $ 38.4 $ 37.9 $ 33.9Finance lease cost: Amortization of right-of-use assets 2.0 2.1 2.2Interest on lease liabilities 0.5 0.6 0.7Total finance lease cost 2.5 2.7 2.9Variable lease cost 10.5 10.6 9.5Total lease cost $ 51.4 $ 51.2 $ 46.3 Supplemental balance sheet information at December 31, 2021 and 2020 related to leases was as follows: December 31, 2021 2020Operating leases: Operating lease right-of-use assets $ 133.1 $ 118.8 Current operating lease liabilities $ 34.0 $ 31.2Non-current operating lease liabilities 107.5 95.9Total operating lease liabilities $ 141.5 $ 127.1 Finance leases: Property, at cost $ 14.0 $ 14.6Accumulated depreciation and amortization (9.2) (8.1)Net property $ 4.8 $ 6.5 Current obligations of finance leases $ 1.9 $ 2.3Finance leases, net of current obligations 4.2 5.7Total finance lease liabilities $ 6.1 $ 8.0 Weighted average remaining lease term: Operating leases 5.0 years 4.7 yearsFinance leases 4.0 years 4.4 yearsWeighted average discount rate: Operating leases 2.5% 2.9%Finance leases 7.8% 7.3% Supplemental cash flow and other information for the years ended December 31, 2021, 2020, and 2019 related to leases was as follows: For the Years Ended December 31, 2021 20202019Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 39.0 $ 37.3 $ 33.5Operating cash flows from finance leases 0.5 0.6 0.7Financing cash flows from finance leases 2.3 2.2 2.1 Right-of-use assets obtained in exchange for lease liabilities: Operating leases(A) $ 54.7 $ 35.3 $ 55.9Finance leases 0.4 0.3 2.0 (A) Includes $15.8 million and $1.6 million of operating leases established as a result of our acquisitions during 2021 and 2020, respectively.

The following deferred tax assets (liabilities) were recorded at December 31: Assets (Liabilities) 2021 2020Pension$ 32.8 $ 47.2Operating lease liabilities 34.4 31.3Postretirement benefits 19.3 20.8Inventory 25.0 12.3Other deferred tax assets 5.8 5.2Payroll accruals 7.2 7.6Bad debt reserves 0.7 0.8Subtotal 125.2 125.2Less: valuation allowances (0.5) (0.6)Deferred tax assets 124.7 124.6Fixed assets (38.8) (34.5)Operating lease right-of-use assets (32.3) (29.1)Other deferred tax liabilities (9.1) (4.9)Computer software (2.4) (2.4)Deferred tax liabilities (82.6) (70.9)Net deferred tax assets$ 42.1 $ 53.7 Deferred income taxes included in non-current assets (liabilities) at December 31 were: 2021 2020Deferred tax assets included in other non-current assets$ 45.2 $ 54.1Deferred tax liabilities included in other non-current liabilities (3.1) (0.4)Total$ 42.1 $ 53.7 Operating loss and tax credit carryforwards included in net deferred tax assets at December 31 were: 2021 2020U.S. Federal(A)$ 0.5 $ 0.5State(A) 0.2 0.3 (A)Expire between 2024 and 2030 We have placed valuation allowances of $0.5 million and $0.6 million for 2021 and 2020, respectively, relating to federal tax credits and state net operating losses that are not expected to be utilized prior to expiration. We have no material undistributed earnings of non-U.S. subsidiaries as of December 31, 2021, due to the one-time transition tax and global intangible low-taxed income (“GILTI”) provisions enacted under the Tax Cuts and Jobs Act (“TCJA”). No additional income taxes have been provided for any outside basis differences inherent in these foreign entities, as these amounts continue to be indefinitely reinvested in foreign operations. We have made an accounting policy election to treat GILTI as a period cost rather than accounting for it as part of deferred taxes. Due to the high-tax exception election made in 2020 and 2021, our GILTI period cost was immaterial in each year. Our federal income tax returns for the tax years 2018 and forward are available for examination by the United States Internal Revenue Service (“IRS”).  The statute of limitation for the 2018 federal return will expire on October 15, 2022, unless extended by consent. Our state income tax returns for 2017 through 2021 remain subject to examination by various state authorities with the latest period closing on December 31, 2026.  We have not extended the statutes of limitations in any state jurisdictions with respect to years prior to 2017. In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law on March 27, 2020. The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss utilization and carryback periods, modifications to net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property (QIP). On December 27, 2020, the Taxpayer Certainty and Disaster Tax Relief Act of 2020 was enacted as part of the Consolidated Appropriations Act, 2021, followed by the American Rescue Plan Act on March 1, 2021. These recent laws, among many other provisions, expand and extend the refundable employee retention tax credits previously made available under the CARES Act and allow a full deduction for certain business meals for the 2021 and 2022 tax years. The CARES Act and subsequent stimulus packages did not have a material impact on our income tax provision for 2020 or 2021. Our unrecognized tax benefits of $1.0 million, $1.7 million, and $1.9 million as of December 31, 2021, 2020, and 2019, respectively, are uncertain tax positions that would impact our effective tax rate if recognized.  We are periodically engaged in tax return examinations, reviews of statute of limitations periods, and settlements surrounding income taxes.  We do not anticipate a material change in unrecognized tax benefits during the next twelve months. Our uncertain tax benefits, and changes thereto, during 2021, 2020, and 2019 were as follows: 2021 2020 2019Balance at January 1,$ 1.7 $ 1.9 $ 2.6Additions based on tax positions related to current year — 0.2 0.2Reductions for tax positions of prior years (0.7) (0.1) (0.1)Settlements — (0.3) (0.8)Balance at December 31,$ 1.0 $ 1.7 $ 1.9 We classify interest expense and penalties as part of our provision for income taxes based upon applicable federal and state interest/underpayment percentages.  We have accrued $0.2 million and $0.3 million in interest and penalties at December 31, 2021 and 2020, respectively. Interest was computed on the difference between the provision for income taxes recognized in accordance with GAAP and the amount of benefit previously taken or expected to be taken in our federal, state, and local income tax returns.

Capital Stock [Abstract]
Capital Stock	10. CAPITAL STOCK Our common stock is 100% owned by active and retired employees, and there is no public trading market for our common stock.  Since 1928, substantially all of the issued and outstanding shares of common stock have been held of record by voting trustees under successive voting trust agreements. Under applicable New York law, a voting trust may not have a term greater than ten years. A new Voting Trust Agreement was established effective March 3, 2017, which expires by its terms on March 1, 2027. At December 31, 2021, approximately 83% of our outstanding common stock was held in the voting trust. The participation of shareholders in the voting trust is voluntary at the time the voting trust is created, but is irrevocable during its term. Shareholders who elect not to participate in the voting trust hold their common stock as shareholders of record. Shareholders may elect to participate in the voting trust at any time during the term of the voting trust. No holder of our common stock or voting trust interests representing our common stock ("common stock", "common shares", or "shares") may sell, transfer or otherwise dispose of any shares without first offering us the option to purchase those shares at the price at which they were issued.  We also have the option to purchase at the issue price the common shares of any shareholder who ceases to be an employee for any reason other than death or "retirement" (as defined in our amended restated certificate of incorporation), and on the first anniversary of any holder's death. In the past, we have always exercised these purchase options and we expect to continue to do so in the foreseeable future. However, we can make no assurance that we will continue to exercise our purchase option in the future.  All outstanding shares have been issued at $20.00 per share. During 2021, eligible employees and qualified retirees subscribed for 1,056,109 shares totaling $21.1 million.  Subscribers elected to make payments under one of the following options: (i) all shares subscribed for on or before January 14, 2022; or (ii) all shares subscribed for in installments paid through payroll deductions (or in certain cases where a subscriber is no longer on our payroll, through direct monthly payments) over an eleven-month period. Common shares were delivered to subscribers as of January 14, 2022, in the case of shares paid for on or before January 14, 2022.  Shares will be issued and delivered to subscribers on a quarterly basis, as of the tenth day of March, June, September, and December, to the extent full payments for shares are made in the case of subscriptions under the installment method. Shown below is a summary of shares purchased and retired by the Company during the three years ended December 31: Shares of Common Stock Purchased Retired 2021 794,227 798,166 2020 824,685 830,338 2019 962,023 957,495 We also have authorized 10,000,000 shares of Delegated Authority Preferred Stock (“preferred stock”), par value one cent ($0.01).  The preferred stock may be issued in one or more series, with the designations, relative rights, preferences, and limitations of shares of each such series being fixed by a resolution of our Board of Directors.  There were no shares of preferred stock outstanding at December 31, 2021 and 2020. On December 12, 2019, our Board of Directors declared at 5% common stock dividend. Each shareholder was entitled to one share of common stock for every ten shares held as of December 16, 2019. The stock was issued on February 7, 2020.

NET INCOME PER SHARE OF COMMON STOCK The computation of net income per share of common stock is based on the average number of common shares outstanding during each year, adjusted in all periods presented for the declaration of a 5% stock dividend declared in 2019. The average number of shares used in computing net income per share of common stock at December 31, 2021, 2020, and 2019 was 22,793,934 shares, 22,642,057 shares, and 22,555,240 shares, respectively.

Revolving Credit Facility At December 31, 2020, we, along with Graybar Canada Limited, our Canadian operating subsidiary (“Graybar Canada”), had an unsecured, five-year, $750.0 million committed revolving credit agreement maturing in August 2023 with Bank of America, N.A. and the other lenders named therein (the “Revolving Credit Facility”), which included a combined letter of credit sub-facility of up to $25.0 million, a U.S. swing-line loan facility of up to $75.0 million, and a Canadian swing-line loan facility of up to $20.0 million.  The Revolving Credit Facility included a $100.0 million sublimit (in U.S. or Canadian dollars) for borrowings by Graybar Canada.  The Revolving Credit Facility contained an accordion feature, which allowed us to request increases in the aggregate borrowing commitments of up to $375.0 million. On August 13, 2021, we, along with Graybar Canada, amended and extended the Revolving Credit Facility, pursuant to the terms and conditions of a Fourth Amendment to Credit Agreement, dated as of August 13, 2021 (the “Amended Credit Agreement”), by and among Graybar, as parent borrower and guarantor, Graybar Canada Limited, as a borrower, the lenders party thereto, Bank of America, N.A. as Domestic Administrative Agent, Domestic Swing Line Lender and Domestic L/C Issuer and Bank of America, N.A., acting through its Canada Branch, as Canadian Administrative Agent, Canadian Swing Line Lender and Canadian L/C Issuer, which includes a combined letter of credit sub-facility of up to $25.0 million, a U.S. swing-line loan facility of up to $75.0 million, and a Canadian swing-line loan facility of up to $20.0 million. The Amended Credit Agreement also includes a $100.0 million sublimit (in U.S. or Canadian dollars) available for borrowings by Graybar Canada. Our borrowing availability under the facility is reduced by the amount of borrowings by Graybar Canada, but we may use the sublimit amount to increase our borrowings, to the extent available. If we were to use available borrowings under the Amended Credit Agreement that included the sublimit amount, then Graybar Canada’s available capacity would be reduced by our use of such amount. The Amended Credit Agreement contains an accordion feature, which allows us to request increases in the aggregate borrowing commitments of up to $375.0 million. Interest on our borrowings under the Revolving Credit Facility will be based on, at the borrower’s election, either (A) (i) the base rate (as defined in the agreement) or (ii) LIBOR (in the case U.S. dollar-denominated borrowings) or (B) (i) the base rate (as defined in the agreement) or (ii) CDOR (in the case of Graybar Canada as borrower with respect to Canadian dollar-denominated borrowings), in each case plus an applicable margin, as determined by the pricing grid set forth in the Amended Credit Agreement. The Amended Credit Agreement added LIBOR fallback language to address the announced future cessation of specified dollar LIBOR tenor settings.  In connection with such a borrowing, the applicable borrower will also select the term of the loan from available tenors, up to six months, or automatically renew with the consent of the lenders.  Swing line loans, which are daily loans, will bear interest at a rate based on, at the borrower’s election, either (i) the base rate or (ii) the daily floating Eurodollar rate (or CDOR, in the case of Graybar Canada with respect to Canadian dollar-denominated borrowings).  In addition to interest payments, there are certain fees and obligations associated with borrowings, swing-line loans, letters of credit and other administrative matters. The five-year Amended Credit Agreement matures in August 2026. Borrowings of Graybar Canada may be in U.S. dollars or Canadian dollars.  The obligations of Graybar Canada are secured by the guaranty of Graybar and any material domestic subsidiaries of Graybar (as defined).  Under no circumstances will Graybar Canada use its borrowings to benefit Graybar or its operations, including without limitation to repay any of Graybar’s obligations under the facility. The Amended Credit Agreement provides for a quarterly commitment fee ranging from 0.25% to 0.40% per annum, subject to adjustment based upon the consolidated leverage ratio for a fiscal quarter, and letter of credit fees ranging from 1.00% to 1.60% per annum payable quarterly, subject to such adjustment.  Borrowings can be either base rate loans plus a margin ranging from 0.00% to 0.60%, or LIBOR loans plus a margin ranging from 1.00% to 1.60%, both subject to adjustment based upon the consolidated leverage ratio, or an alternative benchmark rate. Availability under the Amended Credit Agreement is subject to the accuracy of representations and warranties and absence of a default and, in the case of Canadian borrowings denominated in Canadian dollars, the absence of a material adverse change in the national or international financial markets, which would make it impracticable to lend Canadian dollars. The Amended Credit Agreement contains updated customary affirmative and negative covenants for credit facilities of this type, including limitations on us and all but certain of our subsidiaries with respect to indebtedness (with specified, limited exceptions), liens, changes in the nature of our business, investments, mergers and acquisitions, issuance of equity securities, dispositions of assets and dissolution of certain subsidiaries, transactions with affiliates, as well as securitizations, factoring transactions, and transactions with sanctioned parties or in violation of certain US or Canadian anti-corruption and anti-money laundering laws.  There are also maximum leverage ratio and minimum interest coverage ratio financial covenants to which we will be subject during the term of the Amended Credit Agreement. The Amended Credit Agreement also provides for customary events of default, including a failure to pay principal, interest or fees when due, failure to comply with covenants, the fact that any representation or warranty made by any of the credit parties is materially incorrect, the occurrence of an event of default under certain other indebtedness by us and our subsidiaries, the commencement of certain insolvency or receivership events affecting any of the credit parties, certain actions under the Employee Retirement Income Security Act of 1974 ("ERISA") and the occurrence of a change in control of any of the credit parties (subject to certain permitted transactions as described in the Amended Credit Agreement).  Upon the occurrence of an event of default, the commitments of the lenders may be terminated and all outstanding obligations of the credit parties under the Amended Credit Agreement may be declared immediately due and payable. We were in compliance with all covenants under the Amended Credit Agreement and Revolving Credit Facility as of December 31, 2021 and 2020, respectively. There were $124.2 million and $50.0 million in short-term borrowings under the Amended Credit Agreement and the Revolving Credit Facility, respectively, as of December 31, 2021 and 2020. Short-term borrowings outstanding during the year ended December 31, 2021 ranged from a minimum of no short-term borrowings to a maximum of $124.2 million. Short-term borrowings outstanding during the year ended December 31, 2020 ranged from a minimum of $50.0 million to a maximum of $370.0 million.  The average daily amount of borrowings outstanding under the Amended Credit Agreement and Revolving Credit Facility during 2021 and 2020 amounted to approximately $10.6 million and $191.6 million at weighted-average interest rates 1.15% and 1.55%, respectively.  The weighted-average interest rate for amounts outstanding at December 31, 2021 was 1.11%. At December 31, 2021, we had available unused committed lines of credit under the Amended Credit Agreement amounting to $625.4 million, compared to $699.6 million at December 31, 2020 under the Revolving Credit Facility. Interest expense, net was $1.0 million, $3.6 million, and $5.5 million for the years ended December 31, 2021, 2020, and 2019, respectively. Private Placement Shelf Agreements We have an uncommitted, unsecured $100.0 million private placement shelf agreement (the "Prudential Shelf Agreement") with PGIM, Inc., which is expected to allow us to issue senior promissory notes to affiliates of PGIM, Inc. at fixed rate terms to be agreed upon at the time of any issuance during a three-year issuance period ending in August 2023. We also have an uncommitted, unsecured $150.0 million private placement shelf agreement (the "MetLife Shelf Agreement") with MetLife Investment Management, LLC (formerly known as MetLife Investment Advisors, LLC), and MetLife Investment Management Limited (collectively, “MetLife”) and each other MetLife affiliate that becomes a party to the agreement. After its amendment and extension in June 2021, the MetLife Shelf Agreement is expected to allow us to issue senior promissory notes to MetLife at fixed or floating rate economic terms to be agreed upon at the time of issuance during a three-year period ending in June 2024. On August 13, 2021, we amended each of these uncommitted private placement shelf agreements to conform to specified changes in the Amended Credit Agreement. We remain obligated under a most favored lender clause which is designed to ensure that any notes in the future under the Prudential Shelf Agreement and MetLife Shelf Agreement will continue to be of equal ranking with indebtedness under our Amended Credit Agreement. No notes have been issued under either the Prudential Shelf Agreement or the MetLife Shelf Agreement as of December 31, 2021 and 2020. Each shelf agreement contains representations and warranties of the Company and the applicable lender, events of default and affirmative and negative covenants, customary for agreements of this type.  After the amendment and extension of the Amended Credit Agreement and related amendments to the Prudential Shelf Agreement and MetLife Shelf Agreement, these covenants are substantially similar to those contained in the Amended Credit Agreement, subject to a number of exceptions and qualifications set forth in the applicable shelf agreement. All outstanding obligations of Graybar under one or both of these agreements may be declared immediately due and payable upon the occurrence of an event of default. We were in compliance with all covenants under the Prudential Shelf Agreement and the MetLife Shelf Agreements as of December 31, 2021 and 2020. Letters of Credit We had total letters of credit of $6.1 million outstanding at December 31, 2021, of which $0.4 million were issued under the Amended Credit Agreement. We had total letters of credit of $6.3 million outstanding at December 31, 2020, of which $0.4 million were issued under the Revolving Credit Facility. The letters of credit are issued primarily to support certain workers' compensation insurance policies.

Pension And Other Postretirement Benefits [Abstract]
Pension And Other Postretirement Benefits	13. PENSION AND OTHER POSTRETIREMENT BENEFITS We have a noncontributory defined benefit pension plan (the "Pension Plan") covering substantially all employees first hired prior to July 1, 2015 after the completion of one year of service and 1,000 hours of service.  The Pension Plan provides retirement benefits based on an employee’s final average earnings and years of service.  A supplemental benefit plan provides nonqualified pension benefits for compensation in excess of the IRS compensation limits applicable to the Pension Plan and eligible compensation deferred by a participant. Our funding policy is to make contributions to the Pension Plan, provided that the total annual contributions will not be less than ERISA and the Pension Protection Act of 2006 minimums or greater than the maximum tax-deductible amount, to review the contribution and funding strategy on a regular basis, and to allow discretionary contributions to be made by us from time to time.  The assets of the Pension Plan are invested primarily in fixed income investments and equity securities. We pay nonqualified pension benefits when they are due according to the terms of the supplemental benefit plan. We provide certain postretirement healthcare and life insurance benefits to retired employees.  Substantially all of our employees hired or rehired prior to 2014 may become eligible for postretirement medical benefits if they reach the age and service requirements of the retiree medical plan and retire on a pension (except a deferred pension) under the Pension Plan.  Medical benefits are self-insured and claims are administered through a third party administrator. The cost of coverage is determined based on the annual projected plan costs. The participant's premium or cost is determined based on Company guidelines. Postretirement life insurance benefits are insured through an insurance company. We fund postretirement benefits as incurred, and accordingly, there were no assets held in the postretirement benefits plan at December 31, 2021 and 2020. The following table sets forth information regarding the funded status of our pension and other postretirement benefits as of December 31, 2021 and 2020: Pension Benefits Postretirement Benefits 2021 2020 2021 2020Change in Benefit Obligation: Benefit obligation at beginning of period$ 921.8 $ 825.1 $ 80.9 $ 76.2Service cost 30.2 29.2 2.2 2.1Interest cost 23.9 26.7 1.7 2.4Actuarial (gain) loss (11.6) 134.7 (5.0) 4.9Benefits paid from plan assets (2.5) (2.1) — —Benefits paid from Company assets (1.6) (1.8) (5.6) (5.8)Plan participants' contributions — — 0.9 1.1Administrative expenses paid (1.5) (3.2) — —Settlements (116.8) (86.8) — —Benefit Obligation at End of Period 841.9 921.8 75.1 80.9Change in Plan Assets: Fair value of plan assets at beginning of period 722.0 658.4 — —Actual return on plan assets 39.5 115.7 — —Employer contributions(A) 41.6 41.8 4.7 4.7Plan participants' contributions — — 0.9 1.1Benefits paid(A) (4.1) (3.9) (5.6) (5.8)Administrative expenses paid (1.5) (3.2) — —Settlements (116.8) (86.8) — —Fair Value of Plan Assets at End of Period 680.7 722.0 — —Unfunded Status$ 161.2 $ 199.8 $ 75.1 $ 80.9 (A) Includes $1.6 million and $1.8 million paid from our assets for unfunded nonqualified pension benefits in fiscal years 2021 and 2020, respectively. The accumulated benefit obligation for our Pension Plan was $774.7 million and $844.0 million at December 31, 2021 and 2020, respectively. Amounts recognized in the consolidated balance sheet for the years ended December 31 consist of the following: Pension Benefits Postretirement Benefits 2021 2020 2021 2020Current accrued benefit cost$ 2.1 $ 1.9 $ 6.6 $ 6.8Non-current accrued benefit cost 159.1 197.9 68.5 74.1Net amount recognized$ 161.2 $ 199.8 $ 75.1 $ 80.9  Current accrued benefit cost for both pension benefits and postretirement benefits is included in other current liabilities in the consolidated balance sheets. Non-current accrued benefit cost for pension benefits and postretirement benefits are included in pension liability and postretirement benefits liability, respectively, in the consolidated balance sheets. Amounts recognized in accumulated other comprehensive loss for the years ended December 31, net of tax, consist of the following: Pension Benefits Postretirement Benefits 2021 2020 2021 2020Net actuarial loss$ 166.1 $ 227.9 $ 9.3 $ 13.6Prior service cost — — 0.1 0.1Accumulated other comprehensive loss$ 166.1 $ 227.9 $ 9.4 $ 13.7 The actuarial gain for the Pension Plan in 2021 was primarily related to increases in the discount rate compared to 2020. The actuarial loss for the Pension Plan in 2020 was primarily related to decreases in the discount rate and changes to the lump-sum interest rates used to measure the benefit obligations compared to 2019. Weighted-average assumptions used to determine the actuarial present value of the pension and postretirement benefit obligations as of December 31 are: Pension BenefitsPostretirement Benefits 2021 2020 2021 2020 Discount rate 2.86% 2.62% 2.71% 2.22%Rate of compensation increase 4.38% 4.49% — — Healthcare cost trend on covered charges — — 5.00% 5.00% The net periodic benefit cost for the years ended December 31, 2021, 2020, and 2019 included the following components: Pension Benefits Postretirement BenefitsComponents of Net Periodic Benefit Cost2021 2020 2019 2021 2020 2019Selling, general and administrative expenses: Service cost$ 30.2 $ 29.2 $ 25.6 $ 2.2 $ 2.1 $ 2.0Total selling, general and administrative expenses$ 30.2 $ 29.2 $ 25.6 $ 2.2 $ 2.1 $ 2.0Non-operating expenses: Interest cost 23.9 26.7 30.0 1.7 2.4 2.9Expected return on plan assets (30.6) (32.8) (34.1) — — —Amortization of: Net actuarial loss 32.3 30.2 19.1 0.8 0.7 0.3Settlement charge 30.4 27.7 — — — —Total non-operating expenses$ 56.0 $ 51.8 $ 15.0 $ 2.5 $ 3.1 $ 3.2Net periodic benefit cost$ 86.2 $ 81.0 $ 40.6 $ 4.7 $ 5.2 $ 5.2 During 2021, we made lump-sum pension benefit distributions and purchased nonparticipating annuity contracts exceeding the cumulative amount of service and interest cost components of the net periodic pension cost for the year, which is the settlement accounting threshold. During 2020, we made lump-sum pension benefit distributions exceeding the settlement accounting threshold. Accordingly, we recorded a non-cash pension settlement charge of $30.4 million and $27.7 million in non-operating expenses on our consolidated statements of income for the year ended December 31, 2021 and 2020, respectively. This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within accumulated other comprehensive loss in proportion to the share of the projected benefit obligation that was settled by the lump-sum pension benefit distributions and purchases of the nonparticipating annuity contracts. Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31 were: Pension Benefits Postretirement Benefits 2021 2020 2019 2021 2020 2019 Discount rate2.62% / 2.72% 3.38% / 2.72% 4.31% 2.22% 3.19% 4.16%Expected return on plan assets5.00% 5.50% 5.75% — — — Rate of compensation increase4.32% 4.24% 4.36% — — — Healthcare cost trend on covered charges— — — 5.00% 5.00% 5.00% A discount rate of 2.62% was used as of January 1, 2021 to determine the net periodic benefit cost for the Pension Plan, which was increased to 2.72% effective September 30, 2021 for the remeasurement of the plan liability upon triggering settlement accounting. A discount rate of 3.38% was used as of January 1, 2020 to determine the net periodic benefit cost for the Pension Plan, which was lowered to 2.72% effective September 30, 2020 for the remeasurement of the plan liability upon triggering settlement accounting. The expected return on plan assets assumption for the Pension Plan is a long-term assumption and was determined after evaluating input from both the plan’s actuary and pension fund investment advisors, consideration of macroeconomic conditions, historical rates of return on plan assets, and anticipated current and long-term rates of return on the various classes of assets in which the plan invests. For measurement of the postretirement benefits net periodic cost, a 5.00% annual rate of increase in per capita cost of covered healthcare benefits was assumed for 2021.  The rate was assumed to remain at 5.00% in 2022 and to remain at that level thereafter. We expect to fund $2.0 million for nonqualified pension benefits during 2022. Pension contributions are expected to be $40.0 million in 2022; however, additional contributions may be made at our discretion. Estimated future defined benefit pension and other postretirement benefit plan payments to plan participants for the years ending December 31 are as follows: YearPension‎Benefits Postretirement‎Benefits 2022$ 58.6 $ 6.6 2023 59.3 6.9 2024 58.9 7.3 2025 59.0 7.4 2026 59.2 7.3 2027 to 2031 288.6 31.8 The investment objective of our Pension Plan is to ensure that there are sufficient assets to fund regular pension benefits payable to employees over the long-term life of the plan.  Our Pension Plan seeks to allocate plan assets in a manner that is closely duration-matched with the actuarial projected cash flow liabilities, consistent with prudent standards for preservation of capital, tolerance of investment risk, and maintenance of liquidity. Assets of the qualified pension plan are held by Comerica Bank (the "Trustee"). Our Pension Plan utilizes a liability-driven investment (“LDI”) approach to help meet these objectives. The LDI strategy employs a structured fixed-income portfolio designed to reduce volatility in the plan's future funding requirements and funding status. This is accomplished by using a blend of long duration government, quasi-governmental and corporate fixed-income securities, as well as appropriate levels of equity and alternative investments designed to optimize the plan's liability hedge ratio. Derivatives may also be used on fixed-income investments to manage interest rate exposure, volatility, duration, credit exposures, and asset class allocation. Derivatives are not allowed if the position creates economic portfolio leverage beyond the portfolio’s investment objectives or if used for speculative purposes. In practice, the value of an asset portfolio constructed primarily of fixed income securities is inversely correlated to changes in market interest rates, primarily offsetting changes in the value of the pension benefit obligation caused by changes in the interest rate used to discount plan liabilities. Asset allocation information for the Pension Plan at December 31, 2021 and 2020 is as follows: Investment2021‎Actual‎Allocation 2021‎Target‎Allocation‎Range2020‎Actual‎Allocation 2020‎Target‎Allocation‎RangeEquity securities - U.S. 6%3-10 % 7%3-10 %Equity securities - International 6%2-10 % 10%2-10 %Fixed income investments 55%40-80 % 66%40-80 %Hedge funds 6%2-8 % 5%2-8 %Real assets 5%2-10 % 5%0-15 %Private equity 5%2-8 % 2%0-15 %Other investments 5%0-8 % 4%0-8 %Short-term investments 12%1-10 % 1%1-10 %Total 100%100 % 100%100 % Actual asset allocation may occasionally fall outside of the target allocation range until rebalancing occurs. Certain reclassifications have been made to the classes of plan assets in prior year to conform to the December 31, 2021 presentation due to a change in our investment policy in 2021. The following is a description of the valuation methodologies used for assets held by the Pension Plan measured at fair value: Equity securities - U.S.Equity securities - U.S. consist of investments in U.S. corporate stocks and U.S. equity mutual funds. U.S. equity mutual funds include publicly traded mutual funds and a bank collective fund for ERISA plans. U.S. corporate stocks and U.S. equity mutual funds are primarily large-capitalization stocks (defined as companies with market capitalization of more than $10 billion). U.S. corporate stocks and publicly traded mutual funds are valued at the closing price reported on the active public market in which the individual securities are traded and are classified as Level 1. The bank collective fund for ERISA plans is valued at the net asset value ("NAV") of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Equity securities – InternationalEquity securities - International consist of investments in international corporate stocks, publicly traded mutual funds, and a collective investment trust, and are primarily investments within developed and emerging markets. Investments other than the collective investment trust are valued at the closing price reported on the active public market in which the individual securities are traded and are classified as Level 1. The collective investment trust is valued at the NAV of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Audited financial statements are produced on an annual basis for the collective investment trust. Fixed income investmentsFixed income investments consist of U.S. and international corporate bonds, government and government agency bonds, derivatives, as well as a collective trust that invests in U.S. government debt securities. U.S. and international corporate bonds and government and government agency bonds are valued by independent pricing services using market-based cash flow generators and pricing spread models on both primary and secondary market transactions. As the significant inputs used are observable market inputs, these investments are classified as Level 2. Derivatives could include, but are not limited to, instruments such as U.S. Treasury futures, total returns swaps, and credit default swaps. Derivatives are valued by independent pricing services using direct and observable market inputs and are thus classified as Level 2. The collective trust is valued at the NAV of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Hedge fundsHedge funds consist of investments in various hedge funds structured as fund-of-funds (defined as a single fund that invests in multiple funds). The hedge funds use various investment strategies in an attempt to generate non-correlated returns. A fund-of-funds is designed to help diversify and reduce the risk of the overall portfolio. The hedge funds are valued at the NAV of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Audited financial statements are produced on an annual basis for the hedge funds. Real assets Real assets consist of a diversified mutual fund, and two limited partnerships (“LP”) that invest in real estate. The diversified mutual fund is valued using quoted prices in an active market, and is therefore classified as Level 1. The LP investments are valued at the NAV of units of the trust. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Audited financial statements are produced on an annual basis for the LP investments. Private equityPrivate equity is an asset class that is generally characterized as requiring long-term commitments and where liquidity is typically limited. Private equity investments do not have an actively traded market with readily observable prices. The investments are limited partnerships and are diversified across typical private equity strategies including: buyouts, co-investments, secondary offerings, venture capital, and special situations. Valuations are developed using a variety of proprietary model methodologies. Valuations may be derived from publicly available sources as well as information obtained from each fund's general partner based upon public market conditions and returns. All private equity investments are classified as Level 3, other than a limited partnership valued at the NAV of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. Audited financial statements are produced on an annual basis for the private equity investments. Other investmentsOther investments consist of investments in a private debt fund and a high-yield bond fund. The private debt fund is valued using unobservable inputs with limited trading activity, and is therefore classified as Level 3. The high-yield bond fund is valued using the NAV based on the fair value of the underlying investments held by the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. Audited financial statements are produced on an annual basis for the private debt fund and the high-yield bond fund. Short-term investmentsShort-term investments consist of cash and cash equivalents in a short-term fund which is valued at the NAV of units of the fund. The NAV, as provided by the Trustee, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund. The methods described above may produce fair value calculations that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, while we believe our Pension Plan valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies for determining fair value at December 31, 2021 or 2020. The following tables set forth, by level within the fair value hierarchy, the Pension Plan assets measured at fair value as of December 31, 2021 and 2020: December 31, 2021InvestmentInvestments‎Measured at‎NAV Level 1 Level 2 Level 3 TotalEquity securities - U.S.$ 13.6 $ 27.3 $ — $ — $ 40.9Equity securities - International 13.9 28.4 — — 42.3Fixed income investments 96.1 — 279.7 — 375.8Hedge funds 41.8 — — — 41.8Real assets 16.4 20.3 — — 36.7Private equity 8.2 — — 21.7 29.9Other investments 20.1 — — 11.4 31.5Short-term investments 81.8 — — — 81.8Total$ 291.9 $ 76.0 $ 279.7 $ 33.1 $ 680.7 December 31, 2020InvestmentInvestments‎Measured at‎NAV Level 1 Level 2 Level 3 TotalEquity securities - U.S.$ 17.3 $ 30.6 $ — $ — $ 47.9Equity securities - International 24.9 45.4 — — 70.3Fixed income investments 317.4 — 162.5 — 479.9Hedge funds 36.0 — — — 36.0Real assets 13.6 21.2 — — 34.8Private equity 2.0 — — 13.8 15.8Other investments 22.1 — — 11.4 33.5Short-term investments 3.8 — — — 3.8Total$ 437.1 $ 97.2 $ 162.5 $ 25.2 $ 722.0 Certain reclassifications have been made to the fair value hierarchy in prior year to conform to the December 31, 2021 presentation.

Profit Sharing And Savings Plan [Abstract]
Profit Sharing And Savings Plan	14. PROFIT SHARING AND SAVINGS PLAN We provide a defined contribution profit sharing and savings plan (the "Plan") covering substantially all of our eligible employees with an individual account for each participant.  Employees may make voluntary before-tax and/or after-tax contributions to the saving portion of the Plan, ranging from 2% to 50% of pay, subject to limitations imposed by federal tax law, ERISA, and the Pension Protection Act of 2006. Substantially all employees hired or rehired after July 1, 2015 are eligible to receive a Company matching contribution beginning the first month after the completion of one year of service and 1,000 hours of service. Effective July 1, 2019, eligible employees receive Company matching contributions beginning the first month after the completion of six months of service and 500 hours of service. Effective January 1, 2021, eligible employees receive Company matching contributions beginning the first pay period after the completion of six months of service and 500 hours of service. The Company match is equal to 50% of an eligible employee's before-tax or Roth payroll contribution, up to 6% of pay per payroll period, with a maximum match per payroll period of 3%. The matching contribution expense recognized by us was $4.5 million, $3.8 million, and $2.7 million for the years ended December 31, 2021, 2020 and 2019, respectively. Annual contributions made by us to the profit-sharing portion of the Plan are determined by the Board of Directors at its discretion, and are generally based on the profitability of the Company.  Expense recognized by us under the profit-sharing portion of the Plan was $71.3 million, $46.8 million, and $56.8 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Commitments And Contingencies	15. COMMITMENTS AND CONTINGENCIES Rental expense was $42.9 million, $40.3 million, and $36.4 million in 2021, 2020, and 2019, respectively.  For future minimum rental payments required under operating leases that have either initial or remaining noncancelable lease terms in excess of one year as of December 31, 2021, refer to Note 7, “Leases”. We are subject to various claims, disputes, and administrative and legal matters incidental to our past and current business activities.  As a result, contingencies can arise resulting from an existing condition, situation, or set of circumstances involving an uncertainty as to the realization of a possible loss. Estimated loss contingencies are accrued only if the loss is probable and the amount of the loss can be reasonably estimated.  With respect to a particular loss contingency, it may be probable that a loss has occurred but the estimate of the loss is a wide range.  If we deem an amount within the range to be a better estimate than any other amount within the range, that amount will be accrued. However, if no amount within the range is a better estimate than any other amount, the minimum amount of the range is accrued.  While we believe that none of these claims, disputes or administrative and legal matters will have a material adverse effect on our financial position, these matters are uncertain and we cannot at this time determine whether the financial impact, if any, of these matters will be material to our results of operations in the period in which such matters are resolved or a better estimate becomes available.

Acquisitions	17. ACQUISITIONS In 2021, we completed acquisitions of businesses for a combined preliminary purchase price of $88.7 million in cash, net of cash acquired. The preliminary purchase price allocation resulted in $20.0 million and $32.1 million of tax-deductible goodwill and other intangible assets, respectively. In 2020, we completed an acquisition of a business for a final purchase price of $27.6 million in cash, net of cash acquired. The final purchase price allocation resulted in $7.4 million and $18.1 million of tax deductible goodwill and other intangible assets, respectively. These acquisitions will help Graybar accelerate growth, diversify our business, extend our reach, and enhance our profitability. Since the date of acquisition, the acquired subsidiaries’ results are reflected in our consolidated financial statements. Pro forma results of the acquisitions were not material; therefore, they are not presented.

Summary Of Significant Accoun_2

Summary Of Significant Accounting Policies (Policy)	12 Months Ended

Summary Of Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Graybar and our subsidiary companies.  All material intercompany balances and transactions have been eliminated.  The ownership interests that are held by owners other than the Company are in subsidiaries owned by the Company and are accounted for and reported as noncontrolling interests.
Estimates	Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities.  Actual results could differ from these estimates.
Revenue Recognition	Revenue Recognition Sales revenue is recognized when performance obligations are satisfied, which is typically upon delivery of the product to the customer.  Sometimes product is purchased from the manufacturer and drop-shipped to the customer. We generally take control of the goods when shipped by the manufacturer and then recognize revenue when control of the product transfers to the customer. Revenues recognized are primarily for product sales, but may also include freight and handling charges. Our standard warehouse shipping terms are FOB shipping point, under which control passes to the customer at the time of shipment. We also earn revenue for professional services, general contracting services, and storage services. Such service revenue represented less than 1% of net sales for the years ended December 31, 2021, 2020, and 2019.  Revenue is reported net of all taxes, primarily sales tax, assessed by governmental authorities as a result of revenue-producing transactions.
Outgoing Freight Expenses	Outgoing Freight Expenses We record 95% of outgoing freight expenses as a component of selling, general and administrative expenses.  Total outgoing freight expenses were $78.9 million, $68.8 million, and $68.5 million for the years ended December 31, 2021, 2020, and 2019, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents We account for cash on hand, deposits in banks, and other short-term, highly liquid investments with an original maturity of three months or less as cash and cash equivalents.
Allowance for Credit Losses	Allowance for Credit Losses We perform ongoing credit evaluations of our customers, and a significant portion of our trade receivables is secured by mechanic’s lien or payment bond rights.  We maintain allowances to reflect the expected uncollectability of trade receivables based on past collection history pooled on the aging of the receivables, specific risks identified in the receivables portfolio based on current conditions, and expected future economic conditions when necessary.  Although actual credit losses have historically been within management’s expectations, additional allowances may be required if the financial condition of our customers were to deteriorate.
Merchandise Inventory	Merchandise Inventory Our inventory, comprised entirely of finished goods, is stated at the lower of cost (generally determined using the last-in, first-out (“LIFO”) cost method) or market.  LIFO accounting is a method of accounting that, compared with other inventory accounting methods, generally provides better matching of current costs with current sales. We make provisions for obsolete or excess inventories as necessary to reflect reductions in inventory value.
Vendor Allowances	Vendor Allowances Our agreements with many of our suppliers provide for us to earn volume incentives based on purchases during the agreement period.  Based on the provisions of our vendor agreements, we develop vendor accrual rates by estimating our performance under the agreements and the amounts that will be earned. We perform analyses and review historical trends to ensure the deferred amounts earned are appropriately recorded. Certain vendor agreements contain purchase volume incentives that provide for increased funding when graduated purchase volumes are met. Amounts accrued throughout the year are based on estimates of future activity levels, and could be materially impacted if actual purchase volumes differ. Changes in the estimated amount of incentives are treated as changes in estimate and are recognized in income from operations in the period in which the change in estimate occurs.  In the event that the operating performance of our suppliers were to decline, however, there can be no assurance that amounts earned would be paid or that the volume incentives would continue to be included in future agreements.
Property and Depreciation	Property and Depreciation Property is recorded at cost. Depreciation is expensed on a straight-line basis over the estimated useful lives of the related assets. Interest costs incurred to finance expenditures for major long-term construction projects are capitalized as part of the asset's historical cost and included in property, then depreciated over the useful life of the asset. Leasehold improvements are amortized over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Expenditures for maintenance and repairs are charged to expense when incurred, while the costs of significant improvements, which extend the useful life of the underlying asset, are capitalized.
Fair Value	Fair Value We endeavor to utilize the best available information in measuring fair value.  GAAP has established a fair value hierarchy, which prioritizes the inputs used in measuring fair value.  The tiers in the hierarchy include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own data inputs and assumptions.  We have used fair value measurements to value our pension plan assets.
Foreign Currency Exchange Rate	Foreign Currency Exchange Rate The functional currency for our Canadian subsidiary is the Canadian dollar.  Accordingly, its balance sheet amounts are translated at the exchange rates in effect at the end of each reporting period and its statements of income amounts are translated at the average rates of exchange prevailing during the current period.  Currency translation adjustments are included in accumulated other comprehensive loss.
Goodwill	Goodwill Our goodwill is not amortized, but rather tested annually for impairment.  Goodwill is reviewed annually in the fourth quarter and when circumstances or other events might indicate that impairment may have occurred.  We first perform a qualitative assessment of goodwill impairment. The qualitative assessment considers several factors including the excess fair value over carrying value as of the last quantitative impairment test, the length of time since the last fair value measurement, the current carrying value, market conditions, actual performance compared to forecasted performance, and the current business outlook. If the qualitative assessment indicates that it is more likely than not that goodwill is impaired, the reporting unit is then quantitatively tested for impairment. If a quantitative assessment is required, the fair value is determined using a variety of assumptions including estimated future cash flows of the reporting unit using applicable discount rates.
Definite Lived Intangible Assets	Definite Lived Intangible Assets The cost of intangible assets with determinable useful lives is amortized to reflect the pattern of economic benefits consumed on a straight-line basis over the estimated periods benefited. Customer relationships, trade names and other non-contractual intangible assets with determinable lives are amortized over periods generally ranging from 3 to 20 years. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired.
Income Taxes	Income Taxes We recognize deferred tax assets and liabilities to reflect the future tax consequences of events that have been recognized in the financial statements or tax returns.  A deferred tax asset or liability results from the temporary difference between an item’s carrying value as reflected in the financial statements and its tax basis, and is calculated using enacted applicable tax rates.  We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, a valuation allowance is established.  Changes in the valuation allowance, when recorded, are included in the provision for income taxes in the consolidated financial statements.  We classify interest expense and penalties as part of our provision for income taxes based upon applicable federal and state interest/underpayment percentages. We assess uncertainty regarding tax positions taken in previously filed returns and record reserves in accordance with the guidance under Accounting Standards Codification ("ASC") 740-10, "Accounting for Uncertainty in Income Taxes".
Other Postretirement Benefits	Other Postretirement Benefits We account for postretirement benefits other than pension benefits by accruing the costs of benefits to be provided over the eligible employees’ periods of active service.  These costs are determined on an actuarial basis.  Our consolidated balance sheets reflect the funded status of postretirement benefits.
Pension Plan	Pension Plan We sponsor a noncontributory defined benefit pension plan accounted for by accruing the cost to provide the benefits over the eligible employees’ periods of active service.  These costs are determined on an actuarial basis.  Our consolidated balance sheets reflect the funded status of the defined benefit pension plan.
Leases	Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and non-current operating lease liabilities on our consolidated balance sheets. Amounts related to finance leases are included in property, current portion of long-term debt, and long-term debt on our consolidated balance sheets. ROU assets and lease liabilities are recognized and measured on the date the underlying asset is made available to us. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. We use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. For certain leases, such as real estate and information technology (IT) equipment, we account for the lease and non-lease components as a single lease component. For all other leases, we account for the lease and non-lease components separately. We have elected as an accounting policy not to apply the recognition requirements for short-term leases. Therefore, leases with a term of twelve months or less are not recorded on the consolidated balance sheets. Lease expenses associated with short-term leases are immaterial and are recorded in the consolidated statements of income in selling, general and administrative expenses. Additionally, for certain vehicle leases, we apply a portfolio approach to account for the operating lease ROU assets and liabilities.
Non-operating Expenses	Non-Operating Expenses Non-operating expenses are comprised of interest expense, net and non-service cost components of the net periodic benefit cost for the pension and other postretirement benefit plans. The non-service cost components include interest cost, expected return on plan assets, amortization of net actuarial gains/losses, amortization of prior service costs/gains, and charges due to settlement of certain plan liabilities.
New Accounting Standards	New Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU” or “Update”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” that provides temporary relief to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative rates. This Update is effective for all entities as of March 12, 2020 through December 31, 2022. The guidance on contract modifications, which is applicable to Graybar, can be applied prospectively from any date beginning March 12, 2020 and may also be applied to modifications of existing contracts made earlier in the interim period that includes March 12, 2020. We have evaluated the impact of the adoption of the Update on our contracts and our consolidated financial statements. We do not engage in hedging transactions and we have the option under our Amended Credit Agreement, as defined in Note 12, “Debt”, to continue to use LIBOR until June 30, 2023. As such, this Update does not have a material impact on our contracts and our consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers”, which requires companies to apply ASC 606, “Revenue from Contracts with Customers” to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination. This creates an exception to the general recognition and measurement principle in ASC 805, which uses fair value. The guidance is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption is permitted and the guidance should be applied prospectively. We are currently evaluating the impact of adopting the Update on our consolidated financial statements, and the adoption would be dependent upon whether we pursue any acquisitions in the future.

During 2020, we made lump-sum pension benefit distributions exceeding the settlement accounting threshold. Accordingly, we recorded a non-cash pension settlement charge of $30.4 million and $27.7 million in non-operating expenses on our consolidated statements of income for the year ended December 31, 2021 and 2020, respectively.
