Premium Cap Seal XL can be easily cut in half to custom fit trucks with smaller width front bed rails. The two cut seals can also be doubled up to .340" to fill height gaps from the side rails to the front rail. 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 from .340" to .487" install Front Rail Seal on the cap's front base rail and install Premium Cap Seal on the cap's side base rails. If the height of the gap is extra-large, from .488" to .824" install Front Rail Seal on the truck's front bed rail along with Premium Cap Seal XL installed on the cap's front and side base rails.
