Introducing the all-new, all aluminum A-Series retractable tonneau cover. Built with the same rugged durability as the well-known M-Series, this ground-breaking new product includes a long list of innovative design features that only Roll-N-Lock can provide. The unique, powder-coated aluminum cover body of the A-Series is bound together by a patent pending hinge technology that delivers a nearly impenetrable seam. Unlike other aluminum bed covers that provide only "out of sight, out of mind" security, Roll-N-Lock's A-Series is the real deal. With no exposed rubber seams and a patented tailgate locking system, knife-wielding thieves don't stand a chance. Just like its M-Series counterpart, the A-Series' tonneau cover permits opening or closing in literally seconds, there are no snaps to manipulate or heavy folding panels to lift. A simple rotation of the lock lever and the cover retracts into Roll-N-Lock's ultra-compact housing offering easy and instant access to the entire truck bed.
