Opening the cover is effortless with the heavy-duty torsion spring drive system. Multiple latching positions allow flexible bed access, and the flush handle includes a finger-insulator grip for comfortable operation. The patented built-in tailgate locking system and integrated AutoLock™ feature help secure the tailgate when the cover is closed, providing added protection for tools, equipment, and other cargo.
Installation is simplified with the included clamp-on mounting design, requiring no permanent modifications to the truck bed. The Roll-N-Lock M-Series retractable truck bed cover delivers versatile access, durable construction, and a refined appearance backed by a 3-year limited warranty.
