Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION About Griffon Corporation Griffon Corporation (the “Company” or “Griffon”) is a diversified management and holding company that conducts business through wholly-owned subsidiaries. Griffon oversees the operations of its subsidiaries, allocates resources among them and manages their capital structures. Griffon provides direction and assistance to its subsidiaries in connection with acquisition and growth opportunities as well as in connection with divestitures. In order to further diversify, Griffon also seeks out, evaluates and, when appropriate, will acquire additional businesses that offer potentially attractive returns on capital. Headquartered in New York, N.Y., the Company was founded in 1959 and is incorporated in Delaware. Griffon is listed on the New York Stock Exchange and trades under the symbol GFF. Griffon currently conducts its operations through three reportable segments: • Home & Building Products (“HBP”) consists of two companies, The AMES Companies, Inc. (“AMES”) and Clopay Building Products Company, Inc. (“CBP”): - AMES, founded in 1774, is the leading U.S. manufacturer and a global provider of long-handled tools and landscaping products for homeowners and professionals. - CBP, since 1964, is a leading manufacturer and marketer of residential and commercial garage doors and sells to professional dealers and some of the largest home center retail chains in North America. • Telephonics Corporation ("Telephonics"), founded in 1933, is recognized globally as a leading provider of highly sophisticated intelligence, surveillance and communications solutions for defense, aerospace and commercial customers. • Clopay Plastic Products Company, Inc. ("PPC"), incorporated in 1934, is a global leader in the development and production of embossed, laminated and printed specialty plastic films for hygienic, health-care and industrial products and sells to some of the world's largest consumer products companies. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2016 , which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2016 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2016 . The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated on consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of assets and liabilities of discontinued operations, acquisition assumptions used and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates. Certain amounts in the prior year have been reclassified to conform to current year presentation.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	6 Months Ended
	Mar. 31, 2017
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair values of Griffon’s 2022 senior notes approximated $725,000 on March 31, 2017 . Fair values were based upon quoted market prices (level 1 inputs). On January 17, 2017, Griffon's 4% convertible subordinated notes settled for a total of $173,855 . The total settlement value for the convertible notes was based on the sum of the daily Volume Weighted Average Price multiplied by the conversion rate over a 40-day observation period (level 1 inputs). The settlement value was split between $125,000 in cash and $48,858 , or 1,954,993 shares of common stock issued from treasury. Insurance contracts with values of $3,200 at March 31, 2017 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets on the Consolidated Balance Sheets. Items Measured at Fair Value on a Recurring Basis At March 31, 2017 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,443 ( $1,000 cost basis), were included in Prepaid and other current assets on the Consolidated Balance Sheets. During the first quarter of 2016, the Company settled trading securities with proceeds totaling $715 and recognized a loss of $13 in Other income (expense). Realized and unrealized gains and losses on trading securities are included in Other income in the Consolidated Statements of Operations and Comprehensive Income (Loss). In the normal course of business, Griffon’s operations are exposed to the effects of changes in foreign currency exchange rates. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. During 2017, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade and inter-company liabilities payable in US dollars. At March 31, 2017 , Griffon had $17,500 of Australian dollar contracts at a weighted average rate of $1.30 , which qualified for hedge accounting. These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Accumulated other comprehensive income (loss) ("AOCI") and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred losses of $631 ( $401 , net of tax) at March 31, 2017 and losses of $172 and $821 were recorded in COGS during the quarter and six months ended March 31, 2017 , respectively, for all settled contracts. All contracts expire in 28 to 179 days. At March 31, 2017 , Griffon had $3,300 of Canadian dollar contracts at a weighted average rate of $1.33 . The contracts, which protect Canada operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. For the quarter and six months ended March 31, 2017 , a fair value gain (loss) of $(110) and $1 , respectively, was recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs). Realized gains of $94 and $53 were recorded in Other income during the quarter and six months ended March 31, 2017 , respectively, for all settled contracts. All contracts expire in 28 to 179 days.

As of March 31, 2017, outstanding Senior Notes due totaled $725,000 ; interest is payable semi-annually on March 1 and September 1. The net proceeds of the add-on offering were used to pay down outstanding borrowings under Griffon's Revolving Credit Facility (the "Credit Agreement"). The Senior Notes are senior unsecured obligations of Griffon guaranteed by certain domestic subsidiaries, and subject to certain covenants, limitations and restrictions. On July 20, 2016 and June 18, 2014, Griffon exchanged all of the $125,000 and $600,000 Senior Notes, respectively, for substantially identical Senior Notes registered under the Securities Act of 1933 via an exchange offer. The fair value of the Senior Notes approximated $725,000 on March 31, 2017 based upon quoted market prices (level 1 inputs). In connection with the issuance and exchange of the $125,000 senior notes, Griffon capitalized $3,016 of underwriting fees and other expenses, which will amortize over the term of such notes; Griffon capitalized $10,313 in connection with the previously issued $600,000 senior notes.

The facility includes a letter sub-facility with a limit of $50,000 and a multi-currency sub-facility of $50,000 . The Credit Agreement provides for same day borrowings of base rate loans. Borrowings under the Credit Agreement may be repaid and re-borrowed at any time, subject to final maturity of the facility or the occurrence of an event of default under the Credit Agreement. Interest is payable on borrowings at either a LIBOR or base rate benchmark rate, in each case without a floor, plus an applicable margin, which adjusts based on financial performance. Current margins are 1.25% for base rate loans and 2.25% for LIBOR loans. The Credit Agreement has certain financial maintenance tests including a maximum total leverage ratio, a maximum senior secured leverage ratio and a minimum interest coverage ratio, as well as customary affirmative and negative covenants and events of default. The negative covenants place limits on Griffon's ability to, among other things, incur indebtedness, incur liens, and make restricted payments and investments. Borrowings under the Credit Agreement are guaranteed by Griffon’s material domestic subsidiaries and are secured, on a first priority basis, by substantially all domestic assets of the Company and the guarantors, and a pledge of not greater than 65% of the equity interest in Griffon’s material, first-tier foreign subsidiaries (except that a lien on the assets of Griffon's material domestic subsidiaries securing a limited amount of the debt under the credit agreement relating to Griffon's Employee Stock Ownership Plan ("ESOP") ranks pari passu with the lien granted on such assets under the Credit Agreement; see footnote (e) below).

During 2016, the Company paid quarterly cash dividends of $0.05 per share, totaling $0.20 per share for the year. Dividends paid on shares in the ESOP were used to offset ESOP loan payments and recorded as a reduction of debt service payments and compensation expense. A dividend payable was established for the holders of restricted shares; such dividends will be released upon vesting of the underlying restricted shares.

Compensation expense for restricted stock is recognized ratably over the required service period based on the fair value of the grant, calculated as the number of shares granted multiplied by the stock price on the date of grant and, for performance shares, the likelihood of achieving the performance criteria. Compensation cost related to stock-based awards with graded vesting, generally over a period of three to four years, is recognized using the straight-line attribution method and recorded within SG&A expenses.

Earnings Per Share [Abstract]
EARNINGS PER SHARE (EPS)	EARNINGS PER SHARE (EPS) Basic EPS (and diluted EPS in periods when a loss exists) was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS was calculated by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding plus additional common shares that were issued in connection with stock based compensation and upon the settlement of the 2017 convertible notes. The following table is a reconciliation of the share amounts (in thousands) used in computing earnings per share: Three Months Ended March 31, Six Months Ended March 31, 2017 2016 2017 2016 Weighted average shares outstanding - basic 41,277 41,426 40,307 41,697 Incremental shares from stock based compensation 1,557 2,059 1,740 2,135 Convertible debt matured 2017 395 406 729 895 Weighted average shares outstanding - diluted 43,229 43,891 42,776 44,727 Anti-dilutive options excluded from diluted EPS computation — 416 — 418 On July 14, 2016, Griffon announced that it would settle, upon conversion, up to $125,000 of the conversion value of the 2017 Notes in cash, with amounts in excess of $125,000 , if any, to be settled in shares of Griffon common stock.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Recently adopted accounting pronouncements In March 2016, the FASB issued guidance on Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2016 using either prospective, retrospective or modified retrospective transition method, depending on the area covered in this update. In the fourth quarter of fiscal 2016, the Company early adopted this guidance as of October 1, 2015, using the prospective transition method in order to simplify the accounting for employee share-based payments. As such, all excess tax benefits (“windfalls”) and deficiencies (“shortfalls”) related to employee stock compensation were recognized within income tax expense and included in operating cash flow for the year ended September 30, 2016. Under prior guidance, windfalls were recognized to Capital in excess of par value and shortfalls were only recognized to the extent they exceeded the pool of windfall tax benefits; benefits were recognized in financing activities in the cash flow. The first through third 2016 quarters and related year-to-date periods were adjusted as a result of the adoption. A tax benefit of $2,193 was recognized within income tax expense reflecting the excess tax benefits in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) for the six-month period ended March 31, 2016. Additionally, income tax benefits at settlement of an award were previously reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award's vesting period. As such, there was a $2,193 increase to net cash provided by operating activities and a corresponding decrease to net cash used in financing activities in the accompanying Condensed Consolidated Statement of Cash Flows for six-month period ended March 31, 2016. The remaining provisions of this accounting standard did not have a material impact on the accompanying condensed consolidated financial statements. Newly issued but not yet effective accounting pronouncements In January 2017, the FASB issued guidance that simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those periods and will be effective for the Company beginning in 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In January 2017, the FASB issued guidance that clarifies the definition of a business, which will impact many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The new standard is intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods and will be effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In August 2016, the FASB issued guidance on the Statement of Cash Flows Classification of certain cash receipts and cash payments (a consensus of the FASB Emerging Issues Task Force). This guidance addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance will be effective for the Company beginning in 2019. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In February 2016, the FASB issued guidance on lease accounting requiring lessees to recognize a right-of-use asset and a lease liability for long-term leases. The liability will be equal to the present value of lease payments. This guidance must be applied using a modified retrospective transition approach to all annual and interim periods presented and is effective for the Company beginning in 2020. We are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. In August 2014, the FASB issued guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and related footnote disclosures. Management will be required to evaluate, at each reporting period, whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. This guidance is effective prospectively for annual and interim reporting periods beginning in 2017; implementation of this guidance is not expected to have a material effect on the Company’s financial condition or results of operations. In May 2014, the FASB issued guidance on revenue from contracts with customers. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved, in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. This guidance permits the use of either the retrospective or cumulative effect transition method and is effective for the Company beginning in 2019; early adoption is permitted beginning in 2018. We have not yet selected a transition method and are currently evaluating the impact of the guidance on the Company's financial condition, results of operations and related disclosures. The FASB has also issued the following additional guidance clarifying certain issues on revenue from contracts with customers; Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients and Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing. The Company is currently evaluating this guidance to determine the impact it will have on its consolidated financial statements. The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements, and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.

WARRANTY LIABILITY	WARRANTY LIABILITY Telephonics offers warranties against product defects for periods generally ranging from one to two years, depending on the specific product and terms of the customer purchase agreement. CBP also offers warranties against product defects for periods generally ranging from one to ten years, with limited lifetime warranties on certain door models. Typical warranties require CBP and Telephonics to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience, and periodically assesses its warranty obligations and adjusts the liability as necessary. AMES offers an express limited warranty for a period of ninety days on all products from the date of original purchase unless otherwise stated on the product or packaging. Changes in Griffon’s warranty liability, included in Accrued liabilities, were as follows: Three Months Ended March 31, Six Months Ended March 31, 2017 2016 2017 2016 Balance, beginning of period $ 6,015 $ 6,062 $ 6,322 $ 6,040 Warranties issued and changes in estimated pre-existing warranties 1,213 1,506 2,507 3,008 Actual warranty costs incurred (1,425 ) (1,099 ) (3,026 ) (2,579 ) Balance, end of period $ 5,803 $ 6,469 $ 5,803 $ 6,469

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal and environmental Department of Environmental Conservation of New York State (“DEC”), with ISC Properties, Inc. Lightron Corporation (“Lightron”), a wholly-owned subsidiary of Griffon, once conducted operations at a location in Peekskill in the Town of Cortlandt, New York (the “Peekskill Site”) owned by ISC Properties, Inc. (“ISC”), a wholly-owned subsidiary of Griffon. ISC sold the Peekskill Site in November 1982. Subsequently, Griffon was advised by the DEC that random sampling at the Peekskill Site and in a creek near the Peekskill Site indicated concentrations of solvents and other chemicals common to Lightron’s prior plating operations. ISC then entered into a consent order with the DEC in 1996 (the “Consent Order”) to perform a remedial investigation and prepare a feasibility study. After completing the initial remedial investigation pursuant to the Consent Order, ISC was required by the DEC, and did accordingly conduct over the next several years, supplemental remedial investigations, including soil vapor investigations, under the Consent Order. In April 2009, the DEC advised ISC’s representatives that both the DEC and the New York State Department of Health had reviewed and accepted an August 2007 Remedial Investigation Report and an Additional Data Collection Summary Report dated January 30, 2009. With the acceptance of these reports, ISC completed the remedial investigation required under the Consent Order and was authorized, accordingly, by the DEC to conduct the Feasibility Study required by the Consent Order. Pursuant to the requirements of the Consent Order and its obligations thereunder, ISC, without acknowledging any responsibility to perform any remediation at the Site, submitted to the DEC in August 2009, a draft feasibility study which recommended for the soil, groundwater and sediment media, remediation alternatives having a current net capital cost value, in the aggregate, of approximately $5,000 . In February 2011, DEC advised ISC it has accepted and approved the feasibility study. Accordingly, ISC has no further obligations under the consent order. Upon acceptance of the feasibility study, DEC issued a Proposed Remedial Action Plan (“PRAP”) that sets forth the proposed remedy for the site. The PRAP accepted the recommendation contained in the feasibility study for remediation of the soil and groundwater media, but selected a different remediation alternative for the sediment medium. The approximate cost and the current net capital cost value of the remedy proposed by DEC in the PRAP is approximately $10,000 . After receiving public comments on the PRAP, the DEC issued a Record of Decision (“ROD”) that set forth the specific remedies selected and responded to public comments. The remedies selected by the DEC in the ROD are the same remedies as those set forth in the PRAP. It is now expected that DEC will enter into negotiations with potentially responsible parties to request they undertake performance of the remedies selected in the ROD, and if such parties do not agree to implement such remedies, then the State of New York may use State Superfund money to remediate the Peekskill site and seek recovery of costs from such parties. Griffon does not acknowledge any responsibility to perform any remediation at the Peekskill Site. Improper Advertisement Claim involving Union Tools ® Products. Beginning in December 2004, a customer of AMES had been named in various litigation matters relating to certain Union Tools products. The plaintiffs in those litigation matters asserted causes of action against the customer of AMES for improper advertisement to end consumers. The allegations suggested that advertisements led the consumers to believe that Union Tools’ hand tools were wholly manufactured within boundaries of the United States. The complaints asserted various causes of action against the customer of AMES under federal and state law, including common law fraud. At some point, the customer may seek indemnity (including recovery of its legal fees and costs) against AMES for an unspecified amount. Presently, AMES cannot estimate the amount of loss, if any, if the customer were to seek legal recourse against AMES. Union Fork and Hoe, Frankfort, NY site. The former Union Fork and Hoe property in Frankfort, NY was acquired by Ames in 2006 as part of a larger acquisition, and has historic site contamination involving chlorinated solvents, petroleum hydrocarbons and metals. AMES has entered into an Order on Consent with the New York State Department of Environmental Conservation. While the Order is without admission or finding of liability or acknowledgment that there has been a release of hazardous substances at the site, AMES is required to perform a remedial investigation of certain portions of the property and to recommend a remediation option. At the conclusion of the remediation phase to the satisfaction of the DEC, the DEC will issue a Certificate of Completion. AMES has performed significant investigative and remedial activities in the last few years under work plans approved by the DEC, and the DEC has approved the final remedial investigation report. AMES submitted a Feasibility Study, evaluating a number of remedial options, and recommending excavation and offsite disposal of lead contaminated soils, capping of other areas of the site impacted by other metals and performing limited groundwater monitoring. The DEC accepted the Feasibility Study and is expected to issue a Record of Decision approving the selection of a remedial alternative in 2017. Implementation of the selected remedial alternative is also expected to occur in 2017, or if there are further delays in regulatory approvals, early 2018. AMES has a number of defenses to liability in this matter, including its rights under a previous Consent Judgment entered into between the DEC and a predecessor of AMES relating to the site. U.S. Government investigations and claims Defense contracts and subcontracts, including Griffon’s contracts and subcontracts, are subject to audit and review by various agencies and instrumentalities of the United States government, including among others, the Defense Contract Audit Agency (“DCAA”), the Defense Criminal Investigative Service (“DCIS”), and the Department of Justice ("DOJ") which has responsibility for asserting claims on behalf of the U.S. government. In addition to ongoing audits, Griffon is currently in discussions with the civil division of the U.S. Department of Justice regarding certain amounts the civil division has indicated it believes it is owed from Griffon with respect to certain U.S. government contracts in which Griffon acted as a subcontractor. No claim has been asserted against Griffon in connection with this matter, and Griffon believes that it does not have a material financial exposure in connection with this matter. In general, departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of Griffon, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory or treble damages. U.S. Government regulations provide that certain findings against a contractor may lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges for a company or an operating division or subdivision. Suspension or debarment could have a material adverse effect on Telephonics because of its reliance on government contracts. General legal Griffon is subject to various laws and regulations relating to the protection of the environment and is a party to legal proceedings arising in the ordinary course of business. Management believes, based on facts presently known to it, that the resolution of the matters above and such other matters will not have a material adverse effect on Griffon’s consolidated financial position, results of operations or cash flows.

In accordance with Rule 3-10 of Regulation S-X promulgated under the Securities Act of 1933, presented below are condensed consolidating financial information as of March 31, 2017 and September 30, 2016 and for the three and six months ended March 31, 2017 and 2016 . The financial information may not necessarily be indicative of the results of operations or financial position of the guarantor companies or non-guarantor companies had they operated as independent entities. The guarantor companies and the non-guarantor companies include the consolidated financial results of their wholly-owned subsidiaries accounted for under the equity method. The indenture relating to the Senior Notes (the “Indenture”) contains terms providing that, under certain limited circumstances, a guarantor will be released from its obligations to guarantee the Senior Notes. These circumstances include (i) a sale of at least a majority of the stock, or all or substantially all the assets, of the subsidiary guarantor as permitted by the Indenture; (ii) a public equity offering of a subsidiary guarantor that qualifies as a “Minority Business” as defined in the Indenture (generally, a business the EBITDA of which constitutes less than 50% of the segment adjusted EBITDA of the Company for the most recently ended four fiscal quarters), and that meets certain other specified conditions as set forth in the Indenture; (iii) the designation of a guarantor as an “unrestricted subsidiary” as defined in the Indenture, in compliance with the terms of the Indenture; (iv) Griffon exercising its right to defease the Senior Notes, or to otherwise discharge its obligations under the Indenture, in each case in accordance with the terms of the Indenture; and (v) upon obtaining the requisite consent of the holders of the Senior Notes.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements. As such, they should be read with reference to Griffon’s Annual Report on Form 10-K for the year ended September 30, 2016 , which provides a more complete explanation of Griffon’s accounting policies, financial position, operating results, business properties and other matters. In the opinion of management, these financial statements reflect all adjustments considered necessary for a fair statement of interim results. Griffon’s HBP operations are seasonal; for this and other reasons, the financial results of the Company for any interim period are not necessarily indicative of the results for the full year. The condensed consolidated balance sheet information at September 30, 2016 was derived from the audited financial statements included in Griffon’s Annual Report on Form 10-K for the year ended September 30, 2016 . The condensed consolidated financial statements include the accounts of Griffon and all subsidiaries. Intercompany accounts and transactions have been eliminated on consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. These estimates may be adjusted due to changes in economic, industry or customer financial conditions, as well as changes in technology or demand. Significant estimates include allowances for doubtful accounts receivable and returns, net realizable value of inventories, restructuring reserves, valuation of goodwill and intangible assets, percentage of completion method of accounting, pension assumptions, useful lives associated with depreciation and amortization of intangible and fixed assets, warranty reserves, sales incentive accruals, stock based compensation assumptions, income taxes and tax valuation reserves, environmental reserves, legal reserves, insurance reserves and the valuation of assets and liabilities of discontinued operations, acquisition assumptions used and the accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions Griffon may undertake in the future. Actual results may ultimately differ from these estimates. Certain amounts in the prior year have been reclassified to conform to current year presentation.
Fair Value Measurements	FAIR VALUE MEASUREMENTS The carrying values of cash and equivalents, accounts receivable, accounts and notes payable, and revolving credit and variable interest rate debt approximate fair value due to either the short-term nature of such instruments or the fact that the interest rate of the revolving credit and variable rate debt is based upon current market rates. Applicable accounting guidance establishes a fair value hierarchy requiring the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The accounting guidance establishes three levels of inputs that may be used to measure fair value, as follows: • Level 1 inputs are measured and recorded at fair value based upon quoted prices in active markets for identical assets. • Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. • Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair values of Griffon’s 2022 senior notes approximated $725,000 on March 31, 2017 . Fair values were based upon quoted market prices (level 1 inputs). On January 17, 2017, Griffon's 4% convertible subordinated notes settled for a total of $173,855 . The total settlement value for the convertible notes was based on the sum of the daily Volume Weighted Average Price multiplied by the conversion rate over a 40-day observation period (level 1 inputs). The settlement value was split between $125,000 in cash and $48,858 , or 1,954,993 shares of common stock issued from treasury. Insurance contracts with values of $3,200 at March 31, 2017 are measured and recorded at fair value based upon quoted prices in active markets for similar assets (level 2 inputs) and are included in Prepaid and other current assets on the Consolidated Balance Sheets. Items Measured at Fair Value on a Recurring Basis At March 31, 2017 , trading securities, measured at fair value based on quoted prices in active markets for similar assets (level 2 inputs), with a fair value of $1,443 ( $1,000 cost basis), were included in Prepaid and other current assets on the Consolidated Balance Sheets.

Realized and unrealized gains and losses on trading securities are included in Other income in the Consolidated Statements of Operations and Comprehensive Income (Loss). In the normal course of business, Griffon’s operations are exposed to the effects of changes in foreign currency exchange rates. To manage these risks, Griffon may enter into various derivative contracts such as foreign currency exchange contracts, including forwards and options. During 2017, Griffon entered into several such contracts in order to lock into a foreign currency rate for planned settlements of trade and inter-company liabilities payable in US dollars. At March 31, 2017 , Griffon had $17,500 of Australian dollar contracts at a weighted average rate of $1.30 , which qualified for hedge accounting. These hedges were all deemed effective as cash flow hedges with gains and losses related to changes in fair value deferred and recorded in Accumulated other comprehensive income (loss) ("AOCI") and Prepaid and other current assets, or Accrued liabilities, until settlement. Upon settlement, gains and losses are recognized in the Consolidated Statements of Operations and Comprehensive Income (Loss) in Cost of goods and services ("COGS"). AOCI included deferred losses of $631 ( $401 , net of tax) at March 31, 2017 and losses of $172 and $821 were recorded in COGS during the quarter and six months ended March 31, 2017 , respectively, for all settled contracts. All contracts expire in 28 to 179 days. At March 31, 2017 , Griffon had $3,300 of Canadian dollar contracts at a weighted average rate of $1.33 . The contracts, which protect Canada operations from currency fluctuations for U.S. dollar based purchases, do not qualify for hedge accounting. For the quarter and six months ended March 31, 2017 , a fair value gain (loss) of $(110) and $1 , respectively, was recorded to Other liabilities and to Other income for the outstanding contracts, based on similar contract values (level 2 inputs).
