CRL 1/2" x 7/16" x 4" EPDM Rubber Setting Blocks - 100 Pack - SBEP7

CRL EPDM Rubber Setting Blocks are more durable than Silicone Rubber Setting Blocks, and have better resistance to the effects of weather and ultraviolet rays. CRL EPDM Rubber Blocks are preferred for use in places where there is potential for contact with fuels and/or ozone. The composition of the blocks makes them resilient, so that glass cushioned by them can withstand vibration, shock, high and low temperatures, and heavy wind loads. A variety of sizes are available from stock.

Product Warning: Do not use them with silicone sealants, as there is a potential for bleed-through of color.
