Our Roll N Lock Retractable Tonneau Covers provide customers with secure, watertight bed management, and allows the customer the most versatility with his cargo. Its retractable function permits opening or closing in literally seconds and offers both the rigid vinyl-over-aluminum laminated construction of the M-Series, and a unique, powder-coated aluminum cover body of the A-Series. With a simple rotation of the lock lever, the cover retracts into Roll-N-Lock’s ultra-compact housing and offers easy and instant access to the entire truck bed.
