A durable, locking tonneau cover that's perfect for the pickup owner who wants to achieve more with their truck. The DiamondBack SE seals and secures your bed and is really, really strong. It's built for the unexpected, so you can feel confident you'll be ready for anything. Made from aluminium diamond plate, the DiamondBack SE truck bed cover won't crack like fiberglass or wear out like vinyl. With a 400 lb hauling capacity, you can haul the unexpected or supplies for the weekend project while keeping those everyday items in your bed. A thick neoprene compression gasket runs along the perimeter of the cover to create a barrier to water, snow, or ice, keeping your cargo dry. Rugged, die-cast zinc lock handles on the access panels of a DiamondBack keep your gear secure by actuating 3/8” deadbolt-style rods directly under the bed rails of your truck.
