Some truck caps, that sit on the rails of your truck, are cushioned by a low density foam, sponge or rubber seal. In a very short time, the weight of the cap compresses and deteriorates the inferior seal down to nothing and the vibrations of the cap frame begin to scratch the paint. Dust, fumes and water will invade your truck bed and cargo.
Every time you remove your cap, you will need to replace the low density and/or low quality seal. Using ESI's high quality EPDM rubber seals on your truck cap, you will prevent vibrations, scuff and rust damage, while keeping out the elements. Our seals are made in America.
For the tailgate gap and sidewalls, install our patented Tailgate Seal with Taper Seal® to completely seal out the elements. All truck make and models vary slight.
