The Sterling Fleet outfitters fiberglass 6.5 full size capsule is the only full-coverage truck toppers made with split molding process. That means there are no seams filled with rubber that will later dry out and later leak. This capsule is essentially made of one mold and is completely sealed from the elements, 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 slip-in cap is easily customizable to suit your needs, and can even be converted into our Fiber Optic Splicing Capsule.
