Master Lock. The Truck Bed U-Lock locking system helps safely and conveniently secure items in pickup trucks’ cargo areas. Designed to deter grab-and-go thefts and to secure items that shift in transport, the U-Lock is a semipermanent device installed into the stack hole pockets of pickup truck beds and side rails. Anchored by a weatherproof lock-and-cable system, the U-Lock is constructed of hardened steel, swivels 190 degrees, and has a key cover for protection from the elements. The Truck Bed U-Lock can be used with a range of late-model pickups from Ford, GMC, Chevy, Toyota, and Dodge. 800.464.2088. www.masterlock.com.
