THIRD QUARTER AND NINE MONTHS 2003 OPERATING REVIEW

     ROCKFORD, IL, SEPTEMBER 17, 2003--CLARCOR INC. (NYSE: CLC) reported today
that third quarter 2003 sales increased by 1% and both net earnings and diluted
earnings per share increased by 17% compared to the same quarter in 2002. Third
quarter operating profit increased by 10% and operating margins improved
significantly to 11.9% in 2003 from 10.8% in 2002.

For the nine-month 2003 period, sales increased by 5%, and both net earnings and
diluted earnings per share increased by 20% compared to 2002. Nine-month
operating profit increased by 9%, and operating margins improved to 10.7% in
2003 from 10.2% in 2002.

Norm Johnson, CLARCOR's Chairman and Chief Executive Officer, said, "We had a
very good third quarter with improved operating profit and margins in all three
of our business segments. Sales growth was particularly good in our
Engine/Mobile segment. In our Industrial/Environmental segment, the picture was
more mixed with certain markets exhibiting robust sales growth and other markets
continuing to struggle. Nevertheless, we are particularly pleased with the
margin improvements we have made this year in our Industrial/Environmental
segment as we continue to make progress towards our goal of a 10% segment
operating margin.





"Our Engine/Mobile Filtration segment continues to perform superbly as sales
grew by 5% and operating profit grew by 13% despite challenging economic
conditions in the industry. We believe that we are continuing to increase our
market share in heavy-duty and railroad filtration. Operating margins have
continued to improve as a result of constant attention to our costs and an
increasing ability to leverage our cost structure with increased sales. Looking
to the future, our continuing strategy is to gain additional market share in
those areas where we are under-represented and to roll out a line of new
filtration products. We are particularly excited about the potential of new
products incorporating advanced filter media technology, not only in our
Engine/Mobile segment but also in our Industrial/Environmental segment product
line as well. Internationally, sales of our overseas operations were good in
both U.S. and local currencies, with particularly strong growth in China, South
Africa and continental Europe.

"Our Industrial/Environmental Filtration sales this quarter decreased by 2% from
the third quarter last year, but as I noted above, sales were very uneven across
different markets. As has been true all year, sales were strong for filters sold
to the oil drilling industry and the aviation and aerospace industries. We saw
lower filter and filter equipment sales in capital goods, HVAC and automotive
markets compared to last year's third quarter. We believe that sales to capital
goods markets will begin to show improvement in the fourth quarter, but that
sales to domestic automotive and HVAC markets will remain slow for the rest of
this year. As was true in our Engine/Mobile segment, international sales were
strong throughout Europe and Asia in both U.S. and local currencies. The real
story in this segment is our intense focus on improving margins. Integration
continues in our HVAC operations and we are currently incurring additional costs
to merge the manufacturing, engineering, distribution and administrative
functions of several companies. We are also seeing real progress in improved
manufacturing efficiencies, and in the future we expect to see lower operating
costs. Even with additional costs this year, segment margins overall improved to
6.3% from 5.9% last year, with several of our operations already exceeding our
minimum goal of a 10% operating margin.

"Packaging segment sales improved as flat sheet decorating sales offset a
decline in sales of plastic items. Improving manufacturing efficiencies, though
still less than what we believe we can achieve in this segment, led to an
improvement in operating profit of over 11% compared to the last year's third
quarter. For the remainder of the year, we expect that sales and operating
profit will approximate last year's fourth quarter.

"We are steadily decreasing our borrowings with an additional reduction in
outstanding debt of $23 million during the quarter and a reduction of over $45
million since the end of last year. Capital equipment spending should come in at
approximately $14 million to $17 million for 2003. Foreign currency fluctuations
had an immaterial impact on our third quarter sales and net earnings.



                                        2


"There is no doubt that our biggest challenge, and also our highest priority, is
to grow sales. We are pleased that our sales have grown throughout the recession
and that our margins have consistently improved. Still, growing sales in the
future at a faster rate is our top priority and I want to explain briefly how we
intend to do this:

     o    Diversify our Total Filtration Program into non-automotive sectors:
          Although our Total Filtration Program has been successful, it has
          relied too heavily for growth from its automotive customers. We have
          now assigned salespeople and allocated resources to grow the Program
          more heavily into non-automotive sectors.

     o    Expand presence in under-represented markets: Though we sell to many
          end-use markets in our Engine/Mobile segment, we have always been more
          heavily represented in the over-the-road truck market. We have
          developed new programs to grow sales in agricultural, construction and
          mining markets more intensively than we have in the past. We have also
          developed new products and programs which are designed specifically
          for both our independent distributors and for OEM engine companies.

     o    Expand the product range sold by our branches: By the end of this year
          we will have transferred our twenty air filter branch outlets from our
          HVAC manufacturing companies to our Total Filtration Services (TFS)
          organization. Under TFS, these branches will focus on selling the
          entire range of CLARCOR products instead of their previous focus on
          selling primarily HVAC products.

     o    Increase filter service revenues: Margins from selling filter services
          are generally higher than from selling filter products. To grow our
          service revenues and to more effectively package our filter products
          with our service capabilities, we have created a new and separate
          marketing and sales organization to grow our service business. We will
          initially focus on doing this through our TFS branches, and will then
          expand our filter service line throughout the country.

     o    Leverage the Purolator and Facet brands: We have many brand names,
          some better known than others and some which are known only within
          very narrow industrial sectors. Two of our best known brands are
          "Purolator" and "Facet." We will group our industrial liquid filter
          companies under the brand "Purolator Advanced Filtration." We believe
          that we will grow sales of our industrial liquid filter products
          significantly by leveraging the brand equity that has been created
          from over 40 years under the Purolator and Facet names.

     o    Bring in new management to lead our industrial liquid filter growth:
          We have recently hired Doug Workman, who was formerly General Manager
          and Vice President at Filterite, as President of Purolator Advanced
          Filtration. His background in liquid filtration, particularly in sales
          and marketing, is a significant addition to CLARCOR as he will lead
          the reorganization of our various liquid filter companies into a
          single, dedicated team.



                                       3


     o    Continue the expansion of our operations in China: Eight years ago, we
          established a manufacturing plant in China. This year, sales of its
          products, which are sold in both Chinese and overseas markets,
          increased by more than 20%. We plan on investing additional resources
          to further expand its operations and product capabilities and we see
          China as a major contributor to our growth in the future.

     o    Continue to seek acquisitions: As we have for many years, we will
          continue to look to acquisitions for additional growth. With
          relatively little debt -- our current debt to capital ratio is less
          than 12% -- we have the ability to grow the company substantially if
          the right acquisition becomes available at the right price. We expect
          to expand our current product, technical and geographical capabilities
          through acquisitions and alliances with other companies. No filter
          company has more than an 8% market share and so we expect significant
          consolidation in our industry in the future. We are fortunate that we
          have the skills, experience and financial resources to take advantage
          of this opportunity.

"We now expect full year 2003 diluted earnings per share to be in the $2.00 to
$2.05 range, with fourth quarter diluted earnings per share in the $0.54 to
$0.59 range. We believe that international sales should maintain their momentum
through at least the rest of this year. If the anticipated improvement in
capital equipment spending does finally happen and if, as many economists
expect, the domestic economy continues to improve, we should have a strong
fourth quarter and a good start for fiscal 2004."
