## Overview

The ESI Super Cap Seal 20 FT is a premium EPDM rubber seal designed for truck caps or camper shells weighing up to 200 lbs. Measuring 1.5 inches wide and 0.5 inches thick, this 20-foot seal fills all bed rail gaps on 6.5 ft truck beds, providing a durable moisture and dust barrier. Preferred by professional installers over PVC or foam alternatives, it offers excellent compression resistance and vibration absorption. The kit includes everything needed for installation and is proudly made in the USA.

## Description

For 8ft beds use Super Cap Seal 23ft. 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, 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 XL on the truck's front bed rail.
