Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	CLARCOR Inc. and its subsidiaries (collectively, the “Company” or “CLARCOR”) is a global provider of filtration products, filtration systems and services, and consumer and industrial packaging products. As discussed further in Note 13, the Company has three reportable segments: Engine/Mobile Filtration, Industrial/Environmental Filtration and Packaging. The Consolidated Condensed Financial Statements include all domestic and foreign subsidiaries that were more than 50% owned and controlled as of each respective reporting period presented. All intercompany accounts and transactions have been eliminated.
	The Consolidated Condensed Statements of Earnings, the Consolidated Condensed Statements of Comprehensive Earnings and the Consolidated Condensed Statements of Cash Flows for the periods ended February 28, 2015 and March 1, 2014 and the Consolidated Condensed Balance Sheet as of February 28, 2015 have been prepared by the Company without audit.  The Consolidated Condensed Financial Statements have been prepared on the same basis as those in the Company’s Annual Report on Form 10-K for the fiscal year ended November 29, 2014 (“2014 Form 10-K”).  The November 29, 2014 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2014 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP").  In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows have been made.  The results of operations for the period ended February 28, 2015, are not necessarily indicative of the operating results for the full year.  The information included in this Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the 2014 Form 10-K.
	Cash and Cash Equivalents and Restricted Cash
	Highly liquid investments with an original maturity of three months or less when purchased and that are readily saleable are considered to be cash and cash equivalents.  Restricted cash represents funds held in escrow and cash balances held by German banks as collateral for certain guarantees of overseas subsidiaries.  Restricted cash classified as current corresponds to funds held in escrow that will be used within one year or guarantees that expire within one year.  The Company had $1,295 and $1,294 of noncurrent restricted cash recorded in Other noncurrent assets as of February 28, 2015 and November 29, 2014, respectively, corresponding to guarantees and escrow agreements that expire longer than one year from the dates of the Consolidated Condensed Balance Sheets.
	Inventories
	Inventories are valued at the lower of cost or market primarily determined on the first-in, first-out (“FIFO”) method of inventory costing, which approximates current cost. Inventories are summarized as follows:
		February 28,				November 29,
		2015				2014
	Raw materials	$	108,196			$	101,848
	Work in process	51,158				41,729
	Finished products	138,513				131,141
	Inventories	$	297,867			$	274,718
	Property, Plant and Equipment
	Plant assets classified as Assets held for sale are initially measured at the lesser of the assets' carrying amount or the fair value less costs to sell. Gains or losses are recognized for any subsequent changes in the fair value less cost to sell; however, gains are only recognized to the extent of cumulative losses previously recognized. Plant assets classified as Assets held for sale are not depreciated. At February 28, 2015, property, plant and equipment of $1,964 related to one facility were classified as Assets held for sale.
	Accumulated Other Comprehensive Loss
	Changes in accumulated other comprehensive loss by component for the three months ended February 28, 2015 are as follows:
		Pension Benefits				Foreign Currency Translation Adjustments			Total
	Balance at November 29, 2014, net of tax	$	(37,667	)		$	(16,413	)	$	(54,080	)
	Other comprehensive loss before reclassifications and tax	(105		)		(16,614		)	(16,719		)
	Tax benefit	21				—			21
	Other comprehensive loss before reclassifications, net of tax	(84		)		(16,614		)	(16,698		)
	Reclassifications, before tax	966			(a)	—			966
	Tax expense	(283		)		—			(283		)
	Reclassifications, net of tax	683				—			683
	Other comprehensive income (loss), net of tax	599				(16,614		)	(16,015		)
	Balance at February 28, 2015, net of tax	$	(37,068	)		$	(33,027	)	$	(70,095	)
	___________
	(a) Includes amortization of prior service cost and net actuarial loss included in net periodic benefit cost (see Note 8) that were reclassified from accumulated other comprehensive loss to selling and administrative expenses.
	Derivative Instruments and Hedging Activities
	The Company is exposed to various market risks that arise from transactions entered into in the normal course of business, including market risks associated with changes in foreign currency exchange rates and changes in interest rates. The Company may make use of derivative instruments to manage certain such risks, including derivatives designated as accounting hedges and/or those utilized as economic hedges which are not designated as accounting hedges. The Company does not hold or issue derivatives for trading or speculative purposes.
	All derivatives are recorded at fair value in the Consolidated Balance Sheets. Each derivative is designated as either a fair value hedge or remains undesignated. Changes in the fair value of derivatives that are designated and effective as fair value hedges are recognized currently in net income. These changes are offset in net income to the extent the hedge was effective by fair value changes related to the risk being hedged on the hedged item. Changes in fair value of undesignated hedges are recognized currently in net income. All ineffective changes in derivative fair values are recognized currently in net income.
	The Company formally documents all relationships between designated hedging instruments and hedged items as well as its risk management objective and strategy for undertaking hedge transactions. Both at inception and on an ongoing basis the hedging instrument is assessed as to its effectiveness. If and when a derivative is determined not to be highly effective as a hedge, or the underlying hedge transaction is no longer likely to occur, the hedge designation is removed, or the derivative is terminated, the hedge accounting discussed above is discontinued. Further information related to derivatives and hedging activities is included in Note 5 of the Notes to Consolidated Financial Statements.
	New Accounting Guidance
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods, and interim periods within that period, beginning after December 15, 2016 (fiscal year 2018 for the Company) and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company has not yet determined the potential effects of the adoption of ASU 2014-09 on its Consolidated Financial Statements.
	In June 2014, the FASB issued ASU 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC 718, Compensation-Stock Compensation, as it relates to such awards. ASU 2014-12 is effective for annual reporting periods and interim periods within that period, beginning after December 15, 2015 (fiscal year 2017 for the Company). The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.

	Business Acquisitions
	Filter Resources
	On December 17, 2014, the Company acquired 100% of the outstanding shares of Filter Resources, Inc., Filtration, Inc. and Fabrication Specialties, Inc. (collectively, "Filter Resources"). The purchase price for Filter Resources was approximately $22,099, which the Company funded with borrowings under the Company's revolving credit agreement.
	Filter Resources has operating facilities located in the Texas gulf coast and Louisiana region, with approximately 75 total employees. The business is engaged in the manufacture and distribution of filtration products for petrochemical, refinery, pipeline and other industrial applications. The operations of Filter Resources have been merged into the Company's PECOFacet group of companies, headquartered in Mineral Wells, Texas. Net sales and operating profit for Filter Resources subsequent to the date it was acquired by the Company for the three months ended February 28, 2015 were $4,047 and $276, respectively. Its results are included as part of the Company's Industrial/Environmental Filtration segment from the date of acquisition.
	A preliminary allocation of the purchase price to the assets acquired and liabilities assumed was made based on available information and incorporating management's best estimates. Assets acquired and liabilities assumed in the transaction were recorded at their estimated acquisition-date fair values. A contingent liability for a potential earn-out payment to the former owners, based on earnings from certain capital projects, was recorded at its estimated fair value of $1,154, and is included in Other long-term liabilities in the Consolidated Condensed Balance Sheets. The Company assumed long-term debt of the business of $1,250, which was immediately repaid in connection with the closing. The Company is currently in the process of finalizing the valuations of all assets acquired and liabilities assumed. The Company expects to finalize the purchase price allocation within one year of the purchase date.
	The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition of Filter Resources:
	Accounts receivable		$	3,180
	Inventories		2,042
	Other current assets		111
	Property, plant and equipment		574
	Goodwill		12,345
	Intangible assets		10,580
		Total assets acquired	28,832
	Current liabilities		2,646
	Noncurrent liabilities		4,087
		Net assets acquired	$	22,099
	Filter Resources was acquired primarily to expand the Company's access to petrochemical and refinery customers, particularly in the U.S. gulf coast region. Goodwill of $12,345 recorded in connection with the acquisition, which is not deductible for tax purposes, represents the estimated value of such future opportunities. A summary of the intangible assets acquired is shown in the following table:
		Estimated			Weighted average	Amortization
	Identifiable intangible assets	Value			Useful life	Method
	Customer relationships	$	10,500		15 years	Straight-line
	Trademarks	80			1 year	Straight-line
		$	10,580
	CLARCOR Engine Mobile Solutions
	On May 1, 2014, the Company acquired Stanadyne Corporation's diesel fuel filtration business (the “Stanadyne Business”) through the acquisition of the stock of Stanadyne Holdings, Inc. The business, which now operates as “CLARCOR Engine Mobile Solutions,” is a leading supplier of original equipment and replacement fuel filtration products, primarily for heavy-duty diesel engines used in off-road, agricultural and construction applications.
	CLARCOR Engine Mobile Solutions has approximately 200 employees and is headquartered in Windsor, Connecticut, with manufacturing operations in Washington, North Carolina. Its results are included as part of the Company’s Engine/Mobile Filtration segment from the date of acquisition. The purchase price paid was approximately $327,719 in cash (cash to Stanadyne Corporation of $327,719, net of $0 cash acquired), which the Company funded with cash on hand, a $315,000 term loan and $10,000 borrowed under the Company’s revolving credit agreement (see Note 7).
	A preliminary allocation of the purchase price to the assets acquired and liabilities assumed was made based on available information and incorporating management’s best estimates. Assets acquired and liabilities assumed in the transaction were recorded at their estimated acquisition date fair values, while transaction costs associated with the acquisition were expensed as incurred. The Company is currently in the process of finalizing the valuation of the assets acquired and liabilities assumed. The actual allocation of the final purchase price and the resulting effect on income from operations may differ from the unaudited pro forma amounts included herein. The Company expects to finalize the purchase price allocation within one year of the purchase date.
	The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition of CLARCOR Engine Mobile Solutions:
	Accounts receivable		$	19,548
	Inventories		7,257
	Deferred income taxes		4,121
	Property, plant and equipment		10,176
	Goodwill		194,989
	Intangible assets		146,430
		Total assets acquired	382,521
	Current liabilities		8,963
	Other noncurrent liabilities		2,000
	Deferred income taxes		43,839
		Net assets acquired	$	327,719
	The Stanadyne Business was acquired to significantly increase CLARCOR’s presence in the design, manufacture and supply of original equipment diesel fuel filtration products and the related original equipment services aftermarket, while also providing enhanced scale and market presence to support growth for CLARCOR’s other Engine/Mobile Filtration businesses — including the heavy-duty fuel, oil, hydraulic and air filtration products manufactured and marketed by Baldwin Filters — through original equipment customers and services channels. Goodwill of $194,989 recorded in connection with the acquisition, which is not deductible for tax purposes, represents the estimated value of such future opportunities. A summary of the intangible assets acquired is shown in the following table:
		Estimated			Weighted average	Amortization
	Identifiable intangible assets	Value			Useful life	Method
	Customer relationships	$	135,250		13 years	Straight-line

	CLARCOR Industrial Air
	On December 16, 2013, the Company acquired the Air Filtration business of General Electric Company’s (“GE”) Power and Water division through the acquisition of certain assets and the assumption of certain liabilities, as well as the acquisition of the stock of a subsidiary of GE. The business, which now operates as “CLARCOR Industrial Air”, was acquired to significantly increase the Company’s presence in air inlet filtration products for natural gas turbines and to expand the Company’s product offerings, technologies and customer base in industrial air filtration. CLARCOR Industrial Air employs approximately 700 people and is headquartered in Overland Park, Kansas, with manufacturing operations in Missouri and the United Kingdom. Its results are included as part of the Company’s Industrial/Environmental Filtration segment from the date of acquisition. The purchase price paid was approximately $260,312 in cash (cash to GE of $263,758, net of $3,446 cash acquired), which the Company funded with cash on hand, a $100,000 term loan and $50,000 of cash borrowed under the Company’s revolving credit agreement (see Note 7).
	CLARCOR Industrial Air operates primarily in three markets — gas turbine filtration, industrial air filtration, and specialty membranes. In gas turbine filtration, CLARCOR Industrial Air designs and manufactures high performance inlet filter houses and replacement filter elements for gas turbines used in a wide range of applications, including on-shore power generation plants, on-shore and off-shore oil and gas platforms and pipelines, distributed power generation and commercial and military marine applications. In industrial air filtration, CLARCOR Industrial Air designs and manufactures high performance filter elements for use in a variety of industries, sold to a wide range of customers under various trade names. The specialty membrane business designs and manufactures high performance membranes for apparel and microfiltration.
	An allocation of the purchase price to the assets acquired and liabilities assumed was made based on available information and incorporating management’s best estimates. Assets acquired and liabilities assumed in the transaction were recorded at their estimated acquisition date fair values, while transaction costs associated with the acquisition were expensed as incurred. There were no adjustments to these purchase accounting valuation estimates during the three months ended February 28, 2015. The allocation of the purchase price to the assets and liabilities assumed was finalized as of February 28, 2015.
	The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition of CLARCOR Industrial Air:
	Accounts receivable		$	34,453
	Inventories		41,884
	Other current assets		837
	Property, plant and equipment		22,903
	Goodwill		74,324
	Intangible assets		133,020
		Total assets acquired	307,421
	Total liabilities		47,109
	Net assets acquired	$	260,312
The Company believes the CLARCOR Industrial Air business provides it with a strong platform in the gas turbine filtration market from which to grow, both with respect to first-fit applications as well as the aftermarket, and a broad line of products, in-depth customer knowledge and service capabilities with which to grow in various industrial air filtration markets. Goodwill of $74,324 recorded in connection with the CLARCOR Industrial Air acquisition, which is deductible for tax purposes, represents the estimated value of such future opportunities. A summary of the intangible assets acquired, weighted-average useful lives and amortization methods is shown in the following table:
	Estimated			Weighted average	Amortization
Identifiable intangible assets	Value			Useful life	Method
Trade names	$	35,100		Indefinite	Not amortized

Net sales and operating profit for CLARCOR Industrial Air for the three months ended February 28, 2015 and March 1, 2014 (which, in the case of the three-month period ended March 1, 2014, includes the period from December 16, 2013 to March 1, 2014) were as follows:
	Three Months Ended				Three Months Ended

Pro Forma Results for CLARCOR giving effect to the acquisitions of CLARCOR Engine Mobile Solutions and CLARCOR Industrial Air
The following unaudited pro forma information presents the combined results of operations of CLARCOR, CLARCOR Industrial Air and CLARCOR Engine Mobile Solutions as if both acquisitions had been completed on the first day of fiscal 2013. The pro forma information is presented for information purposes only and does not purport to be indicative of the results of operations or future results that would have been achieved if the acquisitions and related borrowings had taken place at the beginning of fiscal 2013. The pro forma information combines the historical results of CLARCOR with the historical results of CLARCOR Industrial Air and CLARCOR Engine Mobile Solutions for the periods presented.
Prior to acquisition by CLARCOR, the business now operated as CLARCOR Industrial Air was a wholly-owned business of GE’s Power and Water division, and the business now operated as CLARCOR Engine Mobile Solutions was a wholly-owned business of Stanadyne Corporation. As such, neither business was a stand-alone entity for financial reporting purposes. Accordingly, the historical operating results of CLARCOR Industrial Air and CLARCOR Engine Mobile Solutions may not be indicative of the results that might have been achieved, historically or in the future, if CLARCOR Industrial Air and CLARCOR Engine Mobile Solutions had been stand-alone entities.
The unaudited pro forma results for the three-month period ended March 1, 2014 include adjustments to amortization charges for acquired intangible assets, depreciation expense, interest expense, and transaction costs incurred, as well as adjustments to cost of sales related to the step-up of inventory to estimated acquisition-date fair values, other income and related tax effects. The unaudited pro forma results do not give effect to any synergies, operating efficiencies or cost savings that may result from these acquisitions. These pro forma amounts are based on a preliminary allocation of the purchase price to estimates of the fair values of the assets acquired and liabilities assumed.

Bekaert Business
On December 3, 2013, the Company acquired from NV Bekaert SA 100% of the outstanding shares of Bekaert Advanced Filtration SA (Belgium), 100% of the outstanding shares of PT Bekaert Advanced Filtration (Indonesia) and certain other assets in India, China and the U.S. (collectively, the “Bekaert Business”). The purchase price was approximately $7,297 in cash (net of cash acquired), which the Company paid with cash on hand.
The Bekaert Business has approximately 170 employees, and manufacturing facilities located in Belgium and Indonesia, as well as sales personnel in North and South America. The business is engaged in the manufacture and supply of engineered metal filters and systems used primarily in the polymer and plastics industry. The Bekaert Business was acquired to expand the Company’s technical capabilities, improve the Company's product offerings and help the Company continue to grow in Europe and in Asia. The business has been merged into the Company’s Purolator Advanced Filtration Group, headquartered in Greensboro, North Carolina. Its results are included as part of the Company’s Industrial/Environmental Filtration segment from the date of acquisition.
An allocation of the purchase price to the assets acquired and liabilities assumed was made based on available information and incorporating management’s best estimates. Assets acquired and liabilities assumed in the transaction were recorded at their estimated acquisition date fair values, while transaction costs associated with the acquisition were expensed as incurred. There were no adjustments to these purchase accounting valuation estimates during the three months ended February 28, 2015. The allocation of the purchase price to the assets and liabilities assumed was finalized as of February 28, 2015.
Acquired finite-lived intangible assets of $2,057 were recorded in connection with the purchase. The $2,815 excess of the fair value of the identifiable assets acquired and liabilities assumed over the purchase price was recorded as a bargain purchase gain and is included in “Other, net” income in the Consolidated Condensed Statements of Earnings. Prior to recording this gain, the Company reassessed its identification of assets acquired and liabilities assumed, including the use of independent valuation experts to assist the Company in appraising the personal property, real property and intangible assets acquired. The Company believes there were several factors that contributed to this transaction resulting in a bargain purchase gain, including the business falling outside of NV Bekaert SA’s core activities and historical losses incurred by the business.
Net sales and operating loss for the Bekaert business (which in the case of the three-month period ended March 1, 2014, includes the period from December 3, 2013 to March 1, 2014) for the three months ended February 28, 2015 and March 1, 2014 were as follows:
	Three Months Ended				Three Months Ended

Investments
The Company owns 30% of BioProcessH2O LLC (“BPH”), a Rhode Island-based manufacturer of industrial waste water and water reuse filtration systems.  During the three months ended February 28, 2015 and March 1, 2014, respectively, the Company did not make any additional investments. The investment, with a carrying amount of $2,836 and $2,918 at February 28, 2015 and November 29, 2014, respectively, included in Other noncurrent assets in the Consolidated Condensed Balance Sheets, is being accounted for under the equity method of accounting.  The carrying amount is adjusted each period to recognize the Company’s share of the earnings or losses of BPH, included in Other, net in the Consolidated Condensed Statements of Earnings, based on the percentage of ownership, as well as the receipt of any dividends. During the three months ended February 28, 2015 and March 1, 2014, the Company did not receive any dividends from BPH.
The Company also owns 14.85% of BioProcess Algae LLC (“Algae”), a Delaware-based company developing technology to grow and harvest algae which can be used to consume carbon dioxide and also be used as a renewable energy source.  During the three months ended February 28, 2015 the Company did not make any additional investments into Algae, and during the three months ended March 1, 2014 the Company invested an additional $473 into Algae. The investment, with a carrying amount of $3,277 at February 28, 2015 and November 29, 2014, respectively, included in Other noncurrent assets, is being accounted for under the cost method of accounting.  Under the cost method, the Company recognizes dividends as income when received and reviews the cost basis of the investment for impairment if factors indicate that a decrease in value of the investment has occurred.  During the three months ended February 28, 2015 and March 1, 2014, the Company did not receive any dividends from Algae.

Redeemable Noncontrolling Interests
In March 2007, the Company acquired an 80% ownership share in Sinfa SA (“SINFA”), a manufacturer of automotive and heavy-duty engine filters based in Casablanca, Morocco.  As part of the purchase agreement, the Company and the noncontrolling owners each have an option to require the purchase of the remaining 20% ownership shares by the Company after December 31, 2012 which would result in SINFA becoming a wholly owned subsidiary.  As of February 28, 2015, neither the Company nor the noncontrolling owners have exercised the purchase option. The remaining 20% of SINFA owned by the noncontrolling owners has been reported as Redeemable noncontrolling interests and classified as mezzanine equity in the Consolidated Condensed Balance Sheets.  The Redeemable noncontrolling interests is reflected at its carrying value, which is greater than its estimated redemption price. If the redemption becomes probable, the Redeemable noncontrolling interests will be accreted to the redemption price, through equity.  The Company has not recorded any accretion to date.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS
	Fair Value Measurements
	The Company measures certain assets and liabilities at fair value as discussed throughout the notes to its quarterly and annual financial statements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.  Fair value measurements are categorized in a hierarchy based upon the observability of inputs used in valuation techniques.  Observable inputs are the highest level and reflect market data obtained from independent sources, while unobservable inputs are the lowest level and reflect internally developed market assumptions.  The Company classifies fair value measurements by the following hierarchy:
	•	Level 1 – Quoted active market prices for identical assets
	•	Level 2 – Significant other observable inputs, such as quoted prices for similar (but not identical) instruments in active markets, quoted prices for identical or similar instruments in markets which are not active and model determined valuations in which all significant inputs or significant value-drivers are observable in active markets
	•	Level 3 – Significant unobservable inputs, such as model determined valuations in which one or more significant inputs or significant value-drivers are unobservable
	Assets or liabilities that have recurring fair value measurements are shown below:

	Foreign exchange contracts, included in Accrued liabilities	$	367	$	—	$	367	$	—
	There were no changes in the fair value determination methods or significant assumptions used in those methods during the three months ended February 28, 2015.  There were no transfers between Level 1 and Level 2 and there were no transfers into or out of Level 3 during the three months ended February 28, 2015. The Company's policy is to recognize transfers on the actual date of transfer. The restricted trust, which is used to fund certain payments for the Company’s U.S. combined nonqualified pension plans, consists of actively traded equity and bond funds.
	The Company is liable for a contingent earn-out established in connection with the acquisition of Filter Resources on December 17, 2014. This earn-out, which is payable to the former owners of Filter Resources, had an acquisition-date estimated fair-value of $1,154, and was recorded as an other long-term liability. The contingent liability for the earn-out will continue to be accounted for and measured at fair value until the contingency is settled during fiscal year 2017. The fair value measurement of the earn-out payment is based on estimated earnings from certain capital projects, which represent significant inputs not observed in the market and thus represents a Level 3 measurement.
	The Company is liable for a contingent earn-out established in connection with the acquisition of TransWeb on December 29, 2010. This earn-out, which is payable to one of the former owners of TransWeb, had an acquisition-date estimated fair value of $1,018, which was recorded as an other long-term liability at that time.  The contingent liability for the earn-out payment will continue to be accounted for and measured at fair value until the contingency is settled during fiscal year 2016.  The fair value measurement of the contingent earn-out payment is based primarily on 2014 and projected 2015 TransWeb adjusted earnings, which represent significant inputs not observed in the market and thus represents a Level 3 measurement. The contingent consideration payment is revalued to its current fair value at each reporting date. The fair value of the TransWeb contingent earn-out payment was $0 at February 28, 2015 and at November 29, 2014, based on the projected adjusted earnings of TransWeb.
	Fair Values of Financial Instruments
	The fair values of the Company’s financial instruments, which are cash and cash equivalents, restricted cash, accounts receivable, the restricted trust and accounts payable and accrued liabilities, approximated the carrying values of those financial instruments at both February 28, 2015 and November 29, 2014.  An expected present value technique is used to estimate the fair value of long-term debt, using a model that discounts future principal and interest payments at interest rates available to the Company at the end of the period for similar debt of the same maturity.  Long-term debt had a fair value estimate of $435,922 and $408,208 at February 28, 2015 and November 29, 2014, respectively. The Company's fair value estimate of its long-term debt represents a Level 2 measurement as it is based on the current interest rates available to the Company for debt with similar remaining maturities.  The carrying value for the long-term debt at February 28, 2015 and November 29, 2014 is $439,505 and $411,563, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging	DERIVATIVE INSTRUMENTS AND HEDGING
	The Company is exposed to various market risks that arise from transactions entered into in the normal course of business. The Company selectively uses derivative instruments to manage certain such risks, including market risks associated with changes in foreign currency exchange rates and changes in interest rates. The Company does not hold or issue derivatives for trading or speculative purposes. A description of each type of derivative utilized by the Company to manage risk is included below. In addition, refer to Note 4 for information related to the fair value measurements utilized by the Company for each derivative type.
	The Company may elect to designate certain derivatives as hedging instruments under the accounting standards for derivatives and hedging. The Company formally documents all relationships between designated hedging instruments and hedged items as well as its risk management objective and strategy for undertaking hedge transactions.
	All derivatives are recognized on the balance sheet at fair value and classified based on the instrument's maturity date. The total notional amount of derivatives outstanding at February 28, 2015 was $84,777, which consists of derivative instruments to manage foreign exchange risk related to inter-company advances, and derivatives to manage the risk of changes in foreign currency exchange rates — principally the Euro and British pound — on certain firm sales commitments expected to be settled at future dates.
	The following table presents the fair values of derivative instruments included within the Consolidated Balance Sheets at February 28, 2015 and November 29, 2014:

	Fair Value Hedges
	The Company is exposed to changes in foreign currency exchange rates on certain unrecognized firm sales commitments expected to be settled at future dates. The Company may use foreign currency forward contracts to manage certain such risks. The Company designates each such contract as a fair value hedge from the date the firm sales commitment and derivative contract are entered into through the date the related sale occurs, at which point the foreign currency forward contract is de-designated as a fair value hedging instrument. All realized and unrealized gains or losses on such foreign currency forward contracts are recognized in income as incurred. Changes in the fair value of the related unrecognized firm sales commitments that arise due to
	fluctuations in foreign currency exchange rates are also reflected in income and as an asset or liability on the Consolidated Balance Sheets.
	The total notional amount of foreign currency contracts designated as fair value hedges outstanding at February 28, 2015 was $1,094. There were no such fair value hedges entered into during the three months ended March 1, 2014. The cash flows associated with the periodic settlement of the Company's fair value hedges are reflected as a component of Cash flows from operating activities in the Consolidated Statements of Cash Flows.
	Undesignated Derivative Instruments
	The Company is exposed to changes in foreign currency exchange rates on certain inter-company advances. The Company may use foreign currency forward contracts to manage certain such risks. These forward contracts are not designated as hedging instruments under the accounting standards for derivatives and hedging. These undesignated instruments are recorded at fair value as an asset or liability on the Consolidated Balance Sheets and all realized and unrealized gains or losses on such foreign currency forward contracts are recognized in income as incurred.
	The total notional amount of such foreign currency contracts not designated as hedging instruments outstanding as of February 28, 2015 was $82,599. Additionally, the total notional amount of foreign currency contracts de-designated as fair value hedges outstanding at February 28, 2015 was $1,084. There were no such foreign currency contracts during the three months ended March 1, 2014. The cash flows associated with the periodic settlement of the Company's undesignated derivative instruments are reflected as a component of Cash flows from operating activities in the Consolidated Statements of Cash Flows.
	Counterparty credit risk
	By using derivative instruments to manage certain of its risk exposures, the Company is subject, from time to time, to credit risk and market risk on such derivative instruments. Credit risk arises from the potential failure of the counterparty to perform under the terms of the derivative instrument. When the fair value of a derivative instrument is positive, the counterparty owes the Company, which creates credit risk for the Company. The Company mitigates this credit risk by entering into transactions with only creditworthy counterparties. Market risk arises from the potential adverse effects on the value of the derivative that result from changes in foreign currency exchange rates or interest rates, depending on the nature of the derivative. The Company mitigates this market risk by establishing and monitoring parameters that limit the types and degrees of market risk that may be undertaken.

The Company believes that no payments will be required resulting from these obligations.
	In the ordinary course of business, the Company also provides routine indemnifications and other guarantees whose terms range in duration and are often not explicitly defined. The Company does not believe these will have a material impact on the results of operations or financial condition of the Company.
	Warranties
	Warranties are recorded as a liability on the balance sheet and as charges to current expense for estimated normal warranty costs and, if applicable, for specific performance issues known to exist on products already sold. The expenses estimated to be incurred are provided at the time of sale and adjusted as needed, based primarily upon experience. Changes in the Company’s warranty accrual, which is included in Other accrued liabilities, are as follows:

	Warranty accrual at end of period	$	9,145		$	11,678
	Warranty accruals added through business acquisitions in the first three months of 2014 relate primarily to the CLARCOR Industrial Air business, whose sales agreements, particularly for air intake filtration systems for heavy-duty gas turbine applications, include product warranties customary for such types of products. Warranty accruals for this business are established for specifically identified warranty issues known to exist on products already sold, and on a non-specific basis based primarily on past experience.

Debt Disclosure [Abstract]
Long-Term Debt	LONG-TERM DEBT
	On April 5, 2012, the Company entered into a five-year multicurrency revolving credit agreement which included a revolving credit facility (the “Credit Facility”) with a group of financial institutions. Under the Credit Facility, the Company may borrow up to $150,000 which includes a $10,000 swing line sub-facility, as well as an accordion feature that allows the Company to increase the Credit Facility by a total of up to $100,000, subject to securing additional commitments from existing lenders or new lending institutions. On November 22, 2013, the Company entered into a credit agreement amendment to include a $100,000 term loan facility (the "Term Loan Facility") and on May 1, 2014, the Company entered into a second credit agreement amendment to include an additional $315,000 to the Term Loan Facility, whose maturity date will be the same as the maturity date of the Credit Facility. At the Company's election, loans made under the Credit Facility and Term Loan Facility bear interest at either (1) a defined base rate, which varies with the highest of the defined prime rate, the federal funds rate, or a specified margin over the one-month London Interbank Offered Rate (“LIBOR”), or (2) LIBOR plus an applicable margin. Swing line loans bear interest at the defined base rate plus an applicable margin. Commitment fees and letter of credit fees are also payable under the Credit Facility. Borrowings under the Credit Facility and Term Loan Facility are unsecured, but are guaranteed by substantially all of the Company's material domestic subsidiaries. The credit agreement also contains certain covenants customary to such agreements, including covenants that place limits on our ability to incur additional debt, require us to maintain levels of interest coverage, and restrict certain changes in ownership, as well as customary events of default.
	At February 28, 2015, there was $395,000 outstanding on the Term Loan Facility with a weighted average interest rate of approximately 1.07% and there was $28,000 outstanding on the Credit Facility with a weighted average interest rate of approximately 0.87% and a remaining borrowing capacity of $105,988 on the Credit Facility. The Credit Facility includes a $50,000 letter of credit sub-facility, against which $16,012 in letters of credit had been issued at both February 28, 2015 and November 29, 2014.

	The Company expects to contribute up to the following amounts to its various plans to pay benefits during 2015:
	U.S. Qualified Plans	$	—
	U.S. Combined Nonqualified Plans	221
	Non-U.S. Plan	394

Income Taxes	INCOME TAXES
	The following is a reconciliation of the beginning and ending amounts of gross unrecognized tax benefits for uncertain tax positions, including positions which impact only the timing of tax benefits.
		Three Months Ended
		February 28,		March 1,
		2015		2014
	Unrecognized tax benefits at beginning of year	$	2,487	$	2,155
	Additions for current period tax positions	175		79
	Changes in interest and penalties	19		33
	Unrecognized tax benefits at end of period	$	2,681	$	2,267
	At February 28, 2015, the amount of unrecognized tax benefit that would impact the effective tax rate, if recognized, was $1,678.  The Company recognizes interest and penalties related to unrecognized benefits in income tax expense. At February 28, 2015, the Company had $289 accrued for the payment of interest and penalties.
	The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease by $250 over the next twelve months as a result of expected settlements with taxing authorities or the lapse of the statue of limitations in certain jurisdictions. Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of settlements, it is possible that there could be other significant changes in the amount of unrecognized tax benefits in the next twelve months; however, the amount cannot be estimated.
	The Company is regularly audited by federal, state and foreign tax authorities.  The Company's federal tax returns for years subsequent to fiscal year 2010 are open for examination. With few exceptions, the Company is no longer subject to income tax examinations by state or foreign tax jurisdictions for years prior to 2009.
	As part of the purchase of the Stanadyne Business on May 1, 2014, the Company acquired approximately $45,500 of federal net operating loss carryforwards and $1,700 of general business credits, which are subject to certain annual restrictions on utilization. These balances are estimated pending the completion and filing of the pre-acquisition federal return of the Stanadyne Business. The Company expects to finalize the purchase price allocation with respect to these attributes within one year of the purchase date.

	Legal Contingencies
	From time to time, the Company is subject to lawsuits, investigations and disputes (some of which involve substantial claimed amounts) arising out of the conduct of its business, including matters relating to commercial transactions, product liability, intellectual property and other matters.  Certain significant items included in these other matters are discussed below.  The Company believes recorded reserves in its Consolidated Condensed Financial Statements are adequate in light of the probable and estimable outcomes of the items discussed below and other applicable matters.  Any recorded liabilities were not material to the Company’s financial position, results of operation or liquidity for the periods presented, and the Company does not currently believe that any pending claims or litigation, including those identified below, will materially affect its financial position, results of operation or liquidity.
	TransWeb/3M
	On May 21, 2010, 3M Company and 3M Innovative Properties (“3M”) brought a lawsuit against TransWeb, LLC ("TransWeb") in the United States District Court for the District of Minnesota, alleging that certain TransWeb products infringe multiple claims of certain 3M patents. Shortly after receiving service of process in this litigation, TransWeb filed its own complaint against 3M in the United States District Court for the District of New Jersey, seeking a declaratory judgment that the asserted patents are invalid and that the products in question do not infringe. 3M withdrew its Minnesota action, and the parties litigated the matter in New Jersey. The litigation in question was filed and underway before the Company acquired TransWeb in December 2010, but the Company assumed the risk of this litigation as a result of the acquisition.
	During the litigation TransWeb sought judgment that (i) the asserted 3M patents are invalid, the TransWeb products in question do not infringe, and the 3M patents are unenforceable due to inequitable conduct by 3M in obtaining the patents, and (ii) 3M violated U.S. federal antitrust laws under theories of Walker Process fraud and sham litigation. Following a 2012 trial in which a six-member jury unanimously found in TransWeb's favor on all counts other than sham litigation, on April 21, 2014 the U.S. District Court for the District of New Jersey issued a ruling in favor of TransWeb and awarded TransWeb approximately $26,147 in damages.
	3M timely exercised its automatic right to appeal the court's judgment to the US Court of Appeals for the Federal Circuit, and the matter is currently under active appeal before such tribunal.
	Other
	The Company is party to various proceedings relating to environmental issues.  The U.S. Environmental Protection Agency and/or other responsible state agencies have designated the Company as a potentially responsible party, along with other companies, in remedial activities for the cleanup of waste sites under the Comprehensive Environmental Response, Compensation, and Liability Act (commonly referred to as the federal Superfund statute).  Additionally, the North Carolina Department of Environmental Protection has identified the property on which one of the Company's subsidiaries, CLARCOR Engine Mobile Solutions, LLC, currently operates as having concentrations of certain chemicals in groundwater that are above regulatory action levels.
	Although it is not certain what future environmental claims, if any, may be asserted in connection with these known environmental matters, the Company currently believes that its potential liability for known environmental matters is not material and that it has adequately reserved for any probable and reasonably estimable liabilities based on the information available to the Company.  However, environmental and related remediation costs are difficult to quantify for a number of reasons, including the number of parties involved, the difficulty in determining the nature and extent of the contamination at issue, the length of time remediation may require, the complexity of the environmental regulation, the continuing advancement of remediation technology, and the potential imposition of joint and several liability on each potentially responsible party for the cleanup.
	In addition to the matters cited above, the Company is involved in legal actions arising in the normal course of business.  The Company records provisions with respect to identified claims or lawsuits when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Claims and lawsuits are reviewed quarterly and provisions are taken or adjusted to reflect the status of a particular matter.
	Other Contingencies
	In the event of a change in control of the Company, termination benefits are likely to be required for certain executive officers and other employees.

Incentive Plans and Stock-Based Compensation	INCENTIVE PLANS AND STOCK-BASED COMPENSATION
	On March 25, 2014, the shareholders of CLARCOR approved the 2014 Incentive Plan, which replaced the 2009 Incentive Plan. The 2014 Incentive Plan allows the Company to grant stock options, restricted stock unit awards, restricted stock, performance awards and other awards to officers, directors and key employees of up to 6,600,000 shares during a ten-year period that ends in April 2024.  Upon share option exercise or restricted stock unit award conversion, the Company issues new shares unless treasury shares are available.  The key provisions of the Company’s stock-based incentive plans are described in Note M of the Company’s Consolidated Financial Statements included in the 2014 Form 10-K.
	Stock Options
	Nonqualified stock options are granted at exercise prices equal to the market price of CLARCOR common stock at the date of grant, which is the date the Company’s Board of Directors approves the grant and the participants receive it.  The Company’s Board of Directors determines the vesting requirements for stock options at the time of grant and may accelerate vesting.  In general, options granted to key employees vest 25% per year beginning at the end of the first year; therefore, they become fully exercisable at the end of four years.  Vesting may be accelerated in the event of retirement, disability or death of a participant or change in control of the Company.  Options granted to non-employee directors vest immediately, however, beginning in 2013 stock-based compensation for the Company's Board of Directors has been in the form of restricted stock, rather than stock options.  All options expire ten years from the date of grant unless otherwise terminated.
	The following table summarizes information related to stock options and stock option exercises during the three months ended February 28, 2015 and March 1, 2014.

	Expected option term in years		5				5
	The expected option term in years selected for options granted during each period presented represents the period of time that the options are expected to be outstanding based on historical data of option holder exercise and termination behavior.  Expected volatilities are based upon historical volatility of the Company’s monthly stock closing prices over a period equal to the expected life of each option grant.  The risk-free interest rate is selected based on yields from U.S. Treasury zero-coupon issues with a remaining term approximately equal to the expected term of the options being valued.  Expected dividend yield is based on the estimated dividend yield determined on the date of issuance.
	Restricted Stock Unit Awards
	The Company’s restricted stock unit awards are considered nonvested share awards.  The restricted stock unit awards require no payment from the employee.  Compensation cost is recorded based on the market price of the stock on the grant date and is recorded equally over the vesting period of four years.  During the vesting period, officers and key employees receive compensation equal to the amount of dividends declared on common shares they would have been entitled to receive had the shares been issued.  Upon vesting, employees may elect to defer receipt of their shares.  There were 8,489 and 19,457 vested and deferred shares at February 28, 2015 and November 29, 2014, respectively.

As of February 28, 2015, there was $2,287 of total unrecognized compensation cost related to restricted stock unit awards which the Company expects to recognize over a weighted-average period of 3.20 years.
Restricted Stock Unit Awards with Performance Conditions
Beginning in 2015, performance awards were issued to officers and certain key employees as an incentive to achieve revenue growth and operating profit margin goals over a three-year period. The awards are in the form of restricted stock units, which vest at the end of the three-year period if the specified sales growth and operating margin goals are achieved. These restricted stock unit awards are considered nonvested share awards.  The restricted stock unit awards require no payment from the employee.  Fair value of the restricted stock units is determined based on the market price of the stock on the grant date. Compensation cost is recorded equally over the three-year period in which the stock units are earned, based on a periodic determination of the probable performance outcome.  There were no vested shares at February 28, 2015 and November 29, 2014, respectively.

Directors' Restricted Stock Compensation
The incentive plans provide for grants of shares of common stock to all non-employee directors for annual incentive awards, and for grants of shares of common stock to all non-employee directors equal to a one-year annual retainer in lieu of cash at the directors’ option. The directors’ rights to the shares vest immediately on the date of grant; however, shares issued on annual retainer fees cannot be sold for a six-month period from the date of grant.  No shares of common stock were issued to non-employee directors during the three months ended February 28, 2015 and March 1, 2014, respectively.

Earnings Per Share and Stock Repurchase Activity	EARNINGS PER SHARE AND STOCK REPURCHASE ACTIVITY
	The Company calculates basic earnings per share by dividing net earnings by the weighted average number of shares outstanding.  Diluted earnings per share reflects the impact of outstanding stock options, restricted stock and other stock-based arrangements.  The FASB has issued guidance requiring unvested share-based payment awards containing nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) be considered participating securities and included in the computation of earnings per share pursuant to the two-class method.  The Company’s unvested restricted stock unit awards discussed in Note 11 qualify as participating securities under this guidance.  However, the unvested restricted stock unit awards do not materially impact the calculation of basic or diluted earnings per share; therefore, the Company does not present the two-class method computation.  The following table provides a reconciliation of the numerators and denominators utilized in the calculation of basic and diluted earnings per share.

	CLARCOR Inc. and its subsidiaries (collectively, the “Company” or “CLARCOR”) is a global provider of filtration products, filtration systems and services, and consumer and industrial packaging products. As discussed further in Note 13, the Company has three reportable segments: Engine/Mobile Filtration, Industrial/Environmental Filtration and Packaging. The Consolidated Condensed Financial Statements include all domestic and foreign subsidiaries that were more than 50% owned and controlled as of each respective reporting period presented. All intercompany accounts and transactions have been eliminated.
	The Consolidated Condensed Statements of Earnings, the Consolidated Condensed Statements of Comprehensive Earnings and the Consolidated Condensed Statements of Cash Flows for the periods ended February 28, 2015 and March 1, 2014 and the Consolidated Condensed Balance Sheet as of February 28, 2015 have been prepared by the Company without audit.  The Consolidated Condensed Financial Statements have been prepared on the same basis as those in the Company’s Annual Report on Form 10-K for the fiscal year ended November 29, 2014 (“2014 Form 10-K”).  The November 29, 2014 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2014 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP").  In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows have been made.  The results of operations for the period ended February 28, 2015, are not necessarily indicative of the operating results for the full year.  The information included in this Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the 2014 Form 10-K.
Cash and Cash Equivalents and Restricted Cash, Policy	Cash and Cash Equivalents and Restricted Cash
	Highly liquid investments with an original maturity of three months or less when purchased and that are readily saleable are considered to be cash and cash equivalents.  Restricted cash represents funds held in escrow and cash balances held by German banks as collateral for certain guarantees of overseas subsidiaries.  Restricted cash classified as current corresponds to funds held in escrow that will be used within one year or guarantees that expire within one year.
Inventories, Policy	Inventories
	Inventories are valued at the lower of cost or market primarily determined on the first-in, first-out (“FIFO”) method of inventory costing, which approximates current cost.
Property, Plant and Equipment, Policy	Property, Plant and Equipment
	Plant assets classified as Assets held for sale are initially measured at the lesser of the assets' carrying amount or the fair value less costs to sell. Gains or losses are recognized for any subsequent changes in the fair value less cost to sell; however, gains are only recognized to the extent of cumulative losses previously recognized. Plant assets classified as Assets held for sale are not depreciated. At February 28, 2015, property, plant and equipment of $1,964 related to one facility were classified as Assets held for sale.
Derivative Instruments and Hedging Activities, Policy	Derivative Instruments and Hedging Activities
	The Company is exposed to various market risks that arise from transactions entered into in the normal course of business, including market risks associated with changes in foreign currency exchange rates and changes in interest rates. The Company may make use of derivative instruments to manage certain such risks, including derivatives designated as accounting hedges and/or those utilized as economic hedges which are not designated as accounting hedges. The Company does not hold or issue derivatives for trading or speculative purposes.
	All derivatives are recorded at fair value in the Consolidated Balance Sheets. Each derivative is designated as either a fair value hedge or remains undesignated. Changes in the fair value of derivatives that are designated and effective as fair value hedges are recognized currently in net income. These changes are offset in net income to the extent the hedge was effective by fair value changes related to the risk being hedged on the hedged item. Changes in fair value of undesignated hedges are recognized currently in net income. All ineffective changes in derivative fair values are recognized currently in net income.
	The Company formally documents all relationships between designated hedging instruments and hedged items as well as its risk management objective and strategy for undertaking hedge transactions. Both at inception and on an ongoing basis the hedging instrument is assessed as to its effectiveness. If and when a derivative is determined not to be highly effective as a hedge, or the underlying hedge transaction is no longer likely to occur, the hedge designation is removed, or the derivative is terminated, the hedge accounting discussed above is discontinued. Further information related to derivatives and hedging activities is included in Note 5 of the Notes to Consolidated Financial Statements.
New Accounting Guidance, Policy	New Accounting Guidance
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods, and interim periods within that period, beginning after December 15, 2016 (fiscal year 2018 for the Company) and early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company has not yet determined the potential effects of the adoption of ASU 2014-09 on its Consolidated Financial Statements.
	In June 2014, the FASB issued ASU 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." ASU 2014-12 requires that a performance target that affects vesting and could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC 718, Compensation-Stock Compensation, as it relates to such awards. ASU 2014-12 is effective for annual reporting periods and interim periods within that period, beginning after December 15, 2015 (fiscal year 2017 for the Company). The Company does not expect the adoption of this guidance to have a material impact on its Consolidated Financial Statements.
