Keep your truck bed dry with the Protrax cover from Applied Products. Constructed of heavy duty aluminum slats, the Protrax cover retracts on sealed ball bearing rollers into a compact spiral canister at the front of the bed. The Protrax has a front cover that is flush with the rolling cover for a low-profile look that streamlines the appearance. The cover features a dependable seal, is key lockable in any position along the rail and has a dual latch locking system underneath the rolling cover. The Protrax cover installs in about an hour and needs no drilling.
