The Trifecta E-Series is a soft folding truck bed cover topped with a durable vinyl material. Its lightweight aluminum frame and extang engineered heavy- duty support bows span the width of the truck bed for added durability. For ease of use and to keep tension to the truck bed, the Trifecta E-Series is engineered with intuitive, spring-loaded tailgate clamps. Drive with the Trifecta E-Series in either the closed or open position. Like all Trifecta covers, the Trifecta E-Series comes fully assembled with a simple no-tools- required installation process. Best of all, the entire cover can be removed in minutes to maximize space for large cargo.
