What sets Roll-N-Lock’s 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.
Cargo Manager®, an optional companion product for Roll-N-Lock® tonneau covers, is a movable truck bed divider that can be positioned every 3″ along the length of the bed to manage and contain lightweight cargo. Controlled from the driver’s side, Cargo Manager is repositioned by simply squeezing the control levers. Cargo Manager’s spring-activated mechanism then automatically pins the divider to each side track in the next nearest slot. When combined with a Roll-N-Lock retractable tonneau cover, this dynamic product combination gives truck owners not only the ability to cover and secure the contents of the truck bed, but also prevents objects from shifting in the bed when stopping or turning abruptly.
