Roll-N-Lockï¿½, the most advanced retractable truck bed cover made, has redefined the rules for truck bed security. 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 covers do not. Youï¿½ll 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, and ï¿½ best of all ï¿½ no worries about the security of your cargo. The Roll-N-Lock retractable bed coverï¿½by far the most sophisticated and versatile truck bed cover made. Roll-N-Lock Corporation was established in 1992 by the management and engineering staff of Solaroll Shade and Shutter Corporation, a leading manufacturer of retractable (rolling) storm shutters since 1974. Many key members of the Roll-N-Lock management and design team have been working together for more than 20 years.
