| Basis of Presentation, Policy                                                       | Basis of PresentationCLARCOR 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 March 1, 2014 and March 2, 2013 and the Consolidated Condensed Balance Sheet as of March 1, 2014 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 30, 2013 (“2013 Form 10-K”).  The November 30, 2013 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2013 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 March 1, 2014, 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 2013 Form 10-K. |

| New Accounting Guidance, Policy                                                     | New Accounting GuidanceIn February 2013, the Financial Accounting Standards Board ("FASB") updated the disclosure requirements for accumulated other comprehensive income ("AOCI").  The updated guidance requires companies to disclose amounts reclassified out of AOCI by component.  The updated guidance does not affect how net income or other comprehensive income are calculated or presented.  The adoption of this guidance on December 1, 2013 did not have a material impact on the Consolidated Financial Statements.  For additional information, refer to the "Accumulated Other Comprehensive Income (Loss)" section of Note 1 above.Revisions to Previously Issued Financial StatementsThe Company revised its Condensed Consolidated Statement of Cash Flows for the three months ended March 2, 2013 to properly reflect payments made for business acquisition-related seller financing amounts.  The revision resulted in a decrease in the previously reported caption "Business acquisitions, net of cash acquired," a cash outflow from investing activities, of approximately $2,281 and an increase in the caption "Payments on long-term debt, including business acquisition-related seller financing," a cash outflow from financing activities, of approximately $2,281.  This revision is not material to the Condensed Consolidated Statement of Cash Flows for the three months ended March 2, 2013 and has no impact on the Condensed Consolidated Balance Sheet, Condensed Consolidated Statement of Earnings or Condensed Consolidated Statement of Comprehensive Earnings.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |
