Sterling’s Mid-Size Truck Cap made from fiberglass is the only full-coverage truck toppers made with split molding process. That mean’s, there’s no seams filled with rubber that will later dry out and later leak.

This capsule is essentially made of a single mold and is completely sealed from the elements and eliminating condensation entry points. Able to be transferred between trucks by lifting from the inside roof, it’s the most durable fiberglass capsule on the market. This is great if you are leasing, or you currently using service bodies. With our mid-size truck cap you can easily transfer to another pick-up. With a 10 year warranty, you don’t have to worry about the additional costs when replacing your pick ups.

Sterling’s mid-size truck Cap is a mid-height cap with an interior clearance of 49.5″ and is compatible with most 8′ domestic truck beds. This slip-in cap comes unaltered but is customizable to your preferences. To maximize storage and accessibility, the addition of interior shelves and reach-through side doors is a popular choice. Safe entry is important, we suggest adding an interior grab handle and access step.
