Product description

For truck caps that require more than 20ft of seal use Super Cap Seal 23ft (ASIN: B00C7VU9BA). Super moisture barrier double bulb seal prevents dust, fumes and water from invading the interior of a truck bed. Easily trims in half 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 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 20ft on the cap's side base rails. If the height of the gap is extra large, from .488" to .875" install Super Cap Seal 20ft or 23ft on the cap's front and side base rails and install Front Rail Seal on the truck's front bed rail. OTHER QUALITY TRUCK CAP SEALS FROM EXTRUDED SOLUTIONS (ESI): Premium Cap Seal XL 23ft (ASIN: B00IPQR63A) measures 2" wide and fills small to medium bed rail gaps, for caps 200 lbs or less. Super Cap Seal XL 23ft (ASIN: B00JAMSLDM) measures 2 1/8" wide and is for trucks with extra wide bed rails, fills all bed rail gaps, for caps over 200 lbs. Ultra Cap Seal 23ft (ASIN: B00MPMBIZW) measures 1 1/2" wide and fills all bed rail gaps, for caps over 200 lbs. IMPORTANT: To completely seal out dust and water install a patented Ultimate Tailgate Seal with Taper Seal to the tailgate gap and sidewalls (ASIN: B00IPQWXZQ). Save and buy the COMBO Pack: Super Cap Seal 23ft and Ultimate Tailgate Seal with Taper Seal (ASIN: B00BQZMB5A). MADE IN USA
