Thacker Manufacturingannounced theHercuLoc Secure Bed Cover. Developed in consultation with fleet managers, the patented cam locking system holds the cover and tailgate securely closed. There are no external locks or latches; when closed it is locked and cannot be pried open. The HercuLoc operates via code-hopping remote control and a self-locking industrial ball screw actuator, or with an optional hard-wired switch in the cab. Built for commercial use, the HercuLoc is all steel and tolerates bed flexing. The truck can be driven at 75 mph with the cover raised. (Thacker Manufacturing, Tucson, Ariz.)
