🔒 ESI Ultra Cap Seal: 1 1/2" x 5/8" EPDM Rubber, 20' Length - Ensures Secure Fit for Caps over 200 lbs Review

I had to use blue masking tape to hold it in place during installation. Then tear off the blue tape before placing the topper on the back of the truck. The pressure itself is great. No leaks.

Luckily the auto shop had a spray adhesive that we could work with instead of trying to send it back and waiting for a replacement. The rubber gasket itself is very good quality, but the fact that the adhesive didn't allow us to put

I ordered this after visiting 3 different dealerships where I found only light foam seals. In my experience, this type of seal loosens after the truck cover has been removed or removed multiple times. This product is great.
