ROLL-N-LOCK's unique, patented features allow you to install this premium quality truck bed cover with CLAMPS! Patented aluminum slats laminated with top grade vinyl retract with smooth, quiet action, and then look terrific when closed. Our integrated tailgate lock latches the cover directly to your tailgate, keeping your cargo locked securely away. Our very compact canister, mounted at the front of the bed, can easily hold the retracted cover neatly out of the way, without taking up much space in your bed.
