Product Description

To determine if you need a Front Rail Seal measure the difference in height from the truck's side bed rails (including, if any, bed rail caps) to the truck's front bed rail. For the cap's side base rails (when using a Front Rail Seal) install one of ESI's high quality 20ft truck cap seals (see choices below). To seal the cap's front and side base rails (not using a Front Rail Seal) install one of the following 20ft or 23ft length truck cap seals: 1 1/2" wide Super Cap Seal 23ft (ASIN: B00C7VU9BA) or Super Cap Seal 20ft (ASIN: B00NCC0SY6) fills all bed rail gaps, use on truck caps that weigh 200 lbs or less. 2" wide Premium Cap Seal XL 23ft (ASIN: B00IPQR63A) or Premium Cap Seal XL 20ft (ASIN: B00NCCX6C2) fills small to medium bed rail gaps, use on truck caps that weigh 200 lbs or less. 2 1/8" wide Super Cap Seal XL 23ft (ASIN: B00BNGBXOC) or Super Cap Seal XL 20ft (ASIN: B00NCCNUJQ) for trucks with extra wide bed rails, fills all bed rail gaps and for caps over 200 lbs. 1 1/2" wide Ultra Cap Seal 23ft (ASIN: B00MPMBIZW) or Ultra Cap Seal 20ft (ASIN: B00NCCDXJ8) fills all bed rail gaps, for caps over 200 lbs. IMPORTANT: To completely seal out dust and water that enter in through the tailgate gap and sidewalls, install a patented Ultimate Tailgate Seal with Taper Seal (ASIN: B00IPQWXZQ). MADE IN USA

Greatly appreciated the alcohol swab to prep the area in addition to the adhesive packet, which is a must to ensure anything sticks to spray-in bed liner.

5.0 out of 5 stars Great for camper tops
Reviewed in the United States on May 16, 2022
Verified Purchase
I bought this product hoping to fill a gap for my tonneau cover. To be fair, the description says camper tops. And I’m sure it will work well for that purpose. It seems to be a very heavy duty and durable product. It would not compress as I had thought , but I was able to place it just behind the tonneau cover and cover the gap in the bedliner. So far it has worked great, and remains solidly in place even without compression. I would definitely recommend this product for camper tops as described!

Would be better with a stronger adhesive stripping. Won't stick to spray coated beds. Had to use a stronger double stick tape to get it to stay in place. Height of seal was perfect with a flat tonneau cover. Sealed great!

This is a great seal for sealing the front rail of my topper. As a suggestion it would be better if it was wider. For my 2011 it would have been better to order 2 to get the width.
