                                   SUPPLEMENT
                            DATED FEBRUARY 23, 1999
                                       TO
                                PROXY STATEMENT
                                       OF
                                  CLARCOR INC.
                            DATED FEBRUARY 18, 1999
 
     Reference is made to the Proxy Statement dated February 18, 1999 of CLARCOR
Inc., a Delaware corporation (the "Company"). The Proxy Statement relates to the
Annual Meeting of Shareholders of the Company to be held March 23, 1999 as set
forth in the Notice of Annual Meeting of Shareholders.
 
     In addition to the election of three directors, the Proxy Statement
proposes an amendment to the Second Restated Certificate of Incorporation of the
Company to increase the authorized number of shares of Preferred Stock of the
Company from 1,300,000 shares to 5,000,000 shares and to increase the authorized
number of shares of Common Stock from 30,000,000 to 60,000,000.
 
     The Proxy Statement erroneously sets forth the vote required to approve
such amendment. The first sentence under the caption "Proposed Amendment to the
Second Restated Certificate of Incorporation -- Voting on the Amendment" is
corrected to read as follows:
 
"Approval of the proposed amendment requires the affirmative vote of the holders
of a majority of the outstanding shares of Common Stock of the Company."
 
     Accordingly, the proposed amendment will not be approved unless the holders
of not less than a majority of the 23,980,125 shares of Common Stock outstanding
on February 10, 1999 (the record date for the meeting) vote in favor of the
amendment.
 
                                          By Order of the Board of Directors
 
                                          Marcia S. Blaylock
