            PREFORMED LINE PRODUCTS ANNOUNCES SIGNIFICANTLY IMPROVED
             FINANCIAL RESULTS FOR THE SECOND QUARTER AND FIRST SIX
                 MONTHS OF 2004 AND A REGULAR QUARTERLY DIVIDEND

Cleveland, Ohio, July 29, 2004 - PREFORMED LINE PRODUCTS COMPANY (NASDAQ: PLPC)
today reported financial results for the second quarter and the first six months
of 2004.

Net income for the quarter ended June 30, 2004 was $2,371,000, or $.41 per
share, representing an increase of 185% over last year's $833,000, or $.14 per
share. Net sales in the second quarter 2004 were $45,884,000, an increase of 15%
from last year's $39,972,000.

Net income for the six months ended June 30, 2004 was $3,735,000, or $.65 per
share, an increase of 95% from the prior year's $1,917,000, or $.33 per share.
Net sales increased 14% to $85,414,000 for the first six months of 2004 compared
to $75,181,000 in 2003.

Rob Ruhlman, President and Chief Executive Officer said, "We experienced a 21%
increase in our domestic sales for the quarter as a result of increased spending
by our energy customers who appear to be working diligently to catch up on
previously deferred projects. We also benefited from certain telecommunication
customers stepping up their fiber to the home programs. Our improvements in the
efficiency of our operations over the past three years softened the impact of
the rising cost of raw materials, particularly steel wire and stainless steel
stampings. We anticipate that the cost of our raw materials will continue to
increase due to high oil prices and excess worldwide demand for steel. We will
continue to work with our customers to make sure that future pricing accurately
reflects the rise in raw material prices as well as our ongoing efforts to
reduce costs while providing the highest quality products and services."

On Tuesday, June 8, 2004, the Board of Directors declared a regular quarterly
dividend in the amount of $.20 per share on the Company's common shares, payable
July 29, 2004 to shareholders of record July 1, 2004.
