Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation, Policy	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, 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.

Restrictions may include legally restricted deposits held as compensating balances against short-term borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits; however, time deposits and short-term certificates of deposit are not generally included in legally restricted deposits.
