Why is it important to use quality high density EPDM rubber seals on your truck cap?
Some truck caps that sit on the rails of your truck and are cushioned by low density foam, sponge or rubber seal or tape.
In a very short time, the weight of the cap compresses the low density seal down to nothing and the vibrations of the cap frame begins to scratch the painted surface of your rails causing the paint to peel. Moisture will get underneath and begin to rust the top surface of your rails. If you ever remove your cap, you will need to replace the low density seal or tape.
Using ESI's higher density rubber seals on your truck cap, you can prevent vibrations, scuff and rust damage and provide the best moisture barrier seal. You will be able to take your cap on and off without having to replace our seals.
