When it comes to protecting your cargo from theft and the elements, you need a tonneau cover you can trust. Roll-N-Lock® is the most rugged, versatile, and secure truck bed cover in the world. From its retractable function, which permits opening or closing in literally seconds, to its rigid, vinyl-over-aluminum laminated construction, this hybrid cover offers everything other tonneau covers do not. You’ll have no snaps to manipulate, no roll or bundle to lash down or stow, no cross bars to negotiate, no fabric shrinkage to struggle with, no folding or solid hinged covers to combat, and – best of all – no worries about the security of your cargo. The Roll-N-Lock retractable truck bed cover – by far, the most advanced tonneau cover made.
