THIRD QUARTER AND NINE MONTHS 2004 OPERATING REVIEW
     FRANKLIN, TN, SEPTEMBER 15, 2004--CLARCOR INC. (NYSE: CLC) reported today
that third quarter 2004 sales increased by 8%, and net earnings and diluted
earnings per share increased by 11% and 9%, respectively, compared to the same
quarter in 2003. Third quarter operating profit increased by 13%, and operating
margins improved to 12.4% in 2004 from 11.9% in 2003.

For the nine-month 2004 period, sales increased by 6%, and net earnings and
diluted earnings per share increased by 15% and 13%, respectively, compared to
2003. Nine-month operating profit increased by 14%, and operating margins
improved to 11.6% in 2004 from 10.7% in 2003.

Third quarter 2004 results were impacted by several factors:
    o   A $0.04 per share cost to relocate the Company's headquarters to
        Franklin, Tennessee.
    o   Costs of $0.01 per share incurred to comply with the provisions of
        Sarbanes-Oxley Section 404.
    o   A $0.01 per share cost to sell a distribution operation in Mexico.

Norm Johnson, CLARCOR's Chairman and Chief Executive Officer, said, "Our third
quarter was another record for CLARCOR with growth in sales and operating profit
in all three of our business segments. Operating margins improved in both our
Industrial/Environmental segment and in our Packaging segment by over one
percentage point each. We are pleased that we once again had a strong quarter
despite costs incurred in our recent headquarters relocation, Sarbanes-Oxley 404
compliance and the sale of a Mexican distribution operation that impacted
earnings per share this quarter by $0.06.



 "Our Engine/Mobile Filtration segment sales grew by over 13% this quarter,
driven by increased product demand from independent aftermarket distribution and
a growing presence in the OEM dealer channel. Both OEM and aftermarket sales of
locomotive filtration products continue to be strong, as they have been
throughout the year. Segment operating margins declined slightly, but would have
been approximately the same as last year's third quarter excluding
Sarbanes-Oxley 404 compliance costs. Internationally, sales of our overseas
operations were strong in both U.S. and local currencies, with particularly
solid growth in China, South Africa, Mexico and continental Europe.

"Our Industrial/Environmental Filtration segment sales this quarter increased by
4% over the third quarter last year, but as has been the case throughout 2004,
sales were very uneven across different markets. Sales were very strong to the
oil drilling, aviation and aerospace industries. HVAC filter sales were weaker
than we had expected, partially due to cooler than normal weather this summer.
Dust collection cartridge sales also improved after a slow first half of the
year and we expect to see a pickup in dust collection system sales later this
year and in 2005, driven by our completely revamped product line. Sales of
specialty filters and filtration systems were also strong this quarter,
particularly small sewage filtration systems and filters used in industrial
process applications. We continue to make progress towards achieving our
objective of a 10% operating margin in this segment and several of our
operations already exceed this goal.

"Packaging segment sales rose by 9%, driven by metal product sales which offset
a decline in sales of plastic products. Improving manufacturing efficiencies led
to an increase in operating profit compared to last year's third quarter. For
the remainder of the year, we expect that sales and operating profit will exceed
last year's fourth quarter.

"We are working on numerous growth programs, probably more now than at any time
during my tenure at CLARCOR. These programs range from the development of new
filter medias for our traditional products, to new filter designs for markets
where we have not previously had a presence. We have more filters under
development in both our filtration segments than ever before. We are also
expanding our technical capabilities, including building a new aviation fuel
test center in Greensboro, North Carolina, and designing a new HVAC filter
research and product development center, which we believe will be the largest
and most sophisticated in the industry. Elsewhere, we are expanding several of
our technical facilities to support further development of our process liquid
filter products.

"Our biggest immediate challenge is the cost and availability of certain raw
materials. Like many industrial companies we are facing increased steel costs,
but we also see increasing costs for other commodities. Similarly, costs for
energy and health care also continue to rise. To offset these, we have and will
continue to raise prices where possible, but also expect to improve productivity
through increased training, automation and facilities integration.




"Fluctuations in currencies did not have a material impact this quarter on
either sales or profitability. Our effective tax rate this quarter was 36.7% and
we expect a 36.5% rate in the fourth quarter. Capital expenditures increased in
the third quarter compared to capital spending earlier this year. For 2004,
capital expenditures should be in the $23 million to $26 million range.

"Cash flow from operations continues to be solid at over $44 million for the
year-to date. With relatively little debt and cash balances of over $26 million,
we have the ability to fund all of our growth programs, continue to pay a
dividend and explore acquisition opportunities. It has been our policy over the
years to maintain a strong and liquid balance sheet and we expect that this will
continue.

"In our previous guidance, we estimated that 2004 earnings per share would be in
the range of $2.30 to $2.40, excluding relocation costs estimated at $0.07 per
share. We now expect 2004 diluted earnings per share to be $2.36 to $2.41, again
excluding relocation costs, which we now estimate will be $0.05 per share. We do
not believe that relocation costs going forward will be significant. Including
all relocation costs, our full year 2004 earnings per share estimate is in the
range of $2.31 to $2.36, and $0.66 to $0.71 for the fourth quarter.
Sarbanes-Oxley implementation costs will continue, but these costs are included
in our estimate for the year.

"We previously announced the acquisition of United EFP, which we expect we will
complete later today. We do not expect that this acquisition will have a
material impact on fourth quarter 2004 results."

CLARCOR will be holding a conference call to discuss third quarter results at
10:00 am CDT on September 15, 2004. Interested parties can listen to the
