REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Plan Committee of the CLARCOR 401(k) Retirement Savings Plan

We have audited the accompanying statements of net assets available for benefits
of the CLARCOR 401(k) Retirement Savings Plan as of December 31, 2003 and 2002,
and the related statements of changes in net assets available for benefits for
the years then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2003 and 2002, and the changes in net assets available for benefits
for the years then ended, in conformity with accounting principles generally
accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

                                                /s/ BDO SEIDMAN, LLP

1. DESCRIPTION OF PLAN        The following brief description of the CLARCOR
                              Inc. (the "Company") 401(k) Retirement Savings
                              Plan (the "Plan") is provided for general
                              information purposes only. Participants should
                              refer to the Summary Plan Description for a more
                              complete description of the Plan's provisions.

   GENERAL                    The Plan is a defined contribution plan covering
                              substantially all domestic employees of the
                              Company who have three months of service and are
                              21 or older. The Plan is subject to the provisions
                              of the Employee Retirement Income Security Act of
                              1974 ("ERISA").

                              Each year, participants may contribute up to 50%
                              of pretax annual compensation, as defined in the
                              Plan, up to the Internal Revenue Code limitations.
                              Participants may also elect to make after-tax
                              contributions to the Plan up to 10% of the
                              participant's compensation, and may also
                              contribute amounts representing distributions from
                              other qualified defined benefit or defined
                              contribution plans. The Company contributes 50% of
                              the first 3% of pretax compensation that a
                              participant contributes to the Plan, with the
                              exception of certain employees, as defined in the
                              Plan, who receive Company contributions up to 40%
                              of the first 6% of pretax contributions that a
                              participant contributes to the Plan.

   PARTICIPANT ACCOUNTS       Each participant's account is credited with the
                              participant's contribution and allocations of the
                              Company's contributions and Plan earnings.
                              Allocations are based on participant account
                              balances, as defined. The only benefit to which a
                              participant is entitled is the benefit that can be
                              provided from the participant's vested account.
                              Participants direct the investment of their
                              contributions into various investment options
                              offered by the Plan. The Plan currently offers a
                              common/collective trust, Company common stock and
                              11 mutual funds as investment options for
                              participants.

                                                   NOTES TO FINANCIAL STATEMENTS

   VESTING                    Participants are immediately vested in their
                              contributions, plus actual earnings thereon.
                              Vesting in the Company's contribution portion of
                              their accounts is based on years of continuous
                              service. A participant is vested as follows:



Total years of service   Vested Percentage
----------------------   -----------------
                      
1                                 0%
2                                 0%
3                               100%


   PARTICIPANT LOANS          Participants may borrow from their accounts a
                              minimum of $1,000 and participants may have only
                              one loan outstanding. Loans are repaid through
                              payroll deductions with principal and interest
                              being credited to the participants' account
                              balances. Loans may not exceed the lesser of 50%
                              of the participant's vested balance or $50,000 and
                              loans are to be repaid over a period of time not
                              to exceed five years, unless used for the purchase
                              of a principal residence, in which case the
                              payback period may not exceed 15 years. The loans
                              are secured by the balance in the participant's
                              account and bear interest at the prime rate plus
                              2% at the time of the loan.

   PAYMENT OF BENEFITS        Upon termination of service, death, disability or
                              retirement, participants, or their beneficiaries,
                              will receive lump-sum benefit payments. Benefits
                              paid are equal to the value of the participant's
                              vested interest in his or her account.

                              Subject to certain provisions specified in the
                              Plan agreement, employed participants may withdraw
                              their after-tax contributions and related
                              earnings. Withdrawals from the Plan may also be
                              made upon circumstances of financial hardship in
                              accordance with provisions specified in the Plan.

                                                                               7

                                                   NOTES TO FINANCIAL STATEMENTS

   FORFEITED ACCOUNTS         Forfeitures are used to reduce future Company
                              contributions. Approximately $ 76,962 and $123,660
                              was used to reduce Company contributions during
                              2003 and 2002, respectively.

   ADMINISTRATIVE EXPENSES    The Company pays substantially all of the Plan's
                              administrative expenses.

2. SUMMARY OF SIGNIFICANT
   ACCOUNTING POLICIES

   BASIS OF ACCOUNTING        The financial statements of the Plan are prepared
                              under the accrual method of accounting.

   USE OF ESTIMATES           The preparation of financial statements in
                              conformity with generally accepted accounting
                              principles requires Plan management to make
                              estimates and assumptions that affect the reported
                              amounts of net assets available for benefits at
                              the date of the financial statements and the
                              changes in net assets available for benefits
                              during the reporting period and, when applicable,
                              disclosure of contingent assets and liabilities at
                              the date of the financial statements. Actual
                              results could differ from those estimates.

   RISKS AND UNCERTAINTIES    The Plan provides for various investment options
                              in any combination of stocks, bonds, fixed income
                              securities, mutual funds and other investment
                              securities. Investment securities are exposed to
                              various risks, such as interest rate, market
                              valuation and credit risks. Due to the level of
                              risk associated with certain investment securities
                              and the level of uncertainty related to changes in
                              the value of investment securities, it is at least
                              reasonably possible that changes in risks could
                              materially affect participants' account balances
                              and the amounts reported in the statement of net
                              assets available for benefits and the statement of
                              changes in net assets available for benefits.
                              Individual participants' accounts bear the risk of
                              loss resulting from fluctuations in fund values.

                                                                               8


                                                                  CLARCOR 401(k)
                                                         RETIREMENT SAVINGS PLAN

                                                   NOTES TO FINANCIAL STATEMENTS

   INVESTMENT VALUATION       The Plan's investments are stated at fair market
                              value. Quoted market prices are used to value
                              investments. Shares of mutual funds and shares of
                              the common/collective trust are valued at the net
                              asset value of shares or units held by the Plan at
                              year end. The Company common stock fund is valued
                              at the year end unit closing price, based on the
                              quoted market price of the Company common stock
                              plus uninvested cash. Participant loans are valued
                              at cost which approximates fair market value.

   PAYMENT OF BENEFITS        Benefits are recorded when paid.

3. SIGNIFICANT INVESTMENTS    The fair market value of individual investments
                              that represent 5% or more of the Plan's net assets
                              are as follows:

4. RELATED-PARTY              The Plan invests in shares of mutual funds managed
   TRANSACTIONS               by an affiliate of Vanguard Fiduciary Trust
                              Company. Vanguard Fiduciary Trust Company acts as
                              trustee for only those investments as defined by
                              the Plan. Transactions in such investments qualify
                              as party-in-interest transactions which are exempt
                              from the prohibited transaction rules.

                              CLARCOR Inc. common stock fund contains shares of
                              common stock issued by the Company. The Company is
                              the plan sponsor as defined by the Plan and,
                              therefore, these transactions qualify as
                              party-in-interest.

                                                                               9


                                                                  CLARCOR 401(k)
                                                         RETIREMENT SAVINGS PLAN

                                                   NOTES TO FINANCIAL STATEMENTS

5. PLAN TERMINATION           Although it has not expressed any intent to do so,
                              the Company has the right under the Plan to
                              discontinue its contributions at any time and to
                              terminate the Plan subject to the provisions of
                              ERISA. In the event of Plan termination,
                              participants will become 100% vested in their
                              employer contributions.

6. TAX STATUS                 The Internal Revenue Service has determined and
                              informed the Company by a letter dated April 8,
                              2002 that the Plan and related trust is designed
                              in accordance with applicable sections of the
                              Internal Revenue Code ("IRC"). Although the Plan
                              has been amended since receiving the determination
                              letter, the Plan Administrator and the Plan's tax
                              counsel believe that the Plan is designed and is
                              currently being operated in compliance with the
                              applicable requirements of the IRC.


7. UBSEQUENT EVENT            Effective January 1, 2004, the Company restated
                              and amended the Plan. Significant changes included
                              an amendment to cover only those eligible
                              employees who elected to continue participation in
                              the CLARCOR Inc. Pension Plan. All other eligible
                              employees may participate in the CLARCOR 401(k)
                              Plan, a "safe harbor" tax-qualified 401(k) plan.

                                                                              10
