Product Review

Easily trims to size to fit trucks with smaller width front bed rails. NOTE: To determine if you need to use a Front Rail Seal 6ft (ASIN: B00C0WVV72) 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. If the height of the gap is .250" or less install Super Cap Seal XL only. If the height of the gap is from .251" to .487" install Front Rail Seal on the cap's front base rail and install Super Cap Seal XL 20ft (ASIN: B00NCCNUJQ) on the cap's side base rails. If the height of the gap is extra-large, from .488" to .875" install Super Cap Seal XL 20ft or 23ft on the cap's front and side base rails and install Front Rail Seal on the truck's front bed rail.
