The Roll-N-Lock E-Series XT combines the E-Series truck bed cover with our T-slot integrated MaxTrak System allowing for unique customization to your truck bed. Pair with your favorite accessories to expand storage space and accessibility for your gear. Mount bikes, coolers, outdoor gear, and more on top of the bed (compatible with most T-slot accessories)! The E-Series XT electric-powered, retractable bed cover offers unmatched convenience and security. Its motor operates with a remote key fob connected to your truck's battery for instantaneous response, stops automatically if it senses objects are in the way and is able to lock in five different positions along the rail. The E-Series XT retractable truck bed cover permits opening or closing in literally seconds, without snaps to manipulate or heavy folding panels to lift. This retractable tonneau cover features a powder-coated, all-aluminum construction for durability in harsh environments. The E-Series XT offers nearly impenetrable security with its a patented four-point locking system that locks the cover instantly and simultaneously with the tailgate. Roll-N-Lock's canister is smaller than any other retractable cover. The Roll-N-Lock E-Series XT electric cover is backed by a US-based customer support team, as well as a 5-year guarantee.
