There are no snaps to manipulate, there is no roll or bundle to lash down or stow, no crossbars 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 cargo. The Roll-N-Lock M-Series tonneau cover is by far the most intelligent and versatile tonneau cover made. What sets Roll-N-Locks M-Series tonneau cover construction apart from the competition is not just the superior quality of our vinyl surface material, but also the design of the slatted aluminum substrate which supports the vinyl. Each Roll-N-Lock slat is rotatively joined by an interlocking hinge. It is the geometry of this uniquely-contoured hinge that lends Roll-N-Lock tonneau covers their strength, quiet, smooth, non-binding movement and roll compactness. Close examination of the Roll-N-Lock hinge in the flat position reveals the fact that each slat is inseparably locked together, yet when rotated, no metal-to-metal contact occurs.California Residents: Prop 65 Warning
