Master Lock's truck bed U-Lock was designed to secure anything you carry in the truck bed and can also prevent cargo from shifting. It's anchored by a semi-permanent weatherproof lock and cable system. Its locking body swivels 190 degrees and fits into the stake-hole pockets--no drilling is required. The U-Lock uses a hardened steel shackle with a lock body and key cover to protect it from the elements, and is currently available for Ford, GM, Dodge, and Toyota pickups.
