Whether it's holding your groceries or your ammunition bag, the Truck Bed Hook holds them in place and securely. Using the patent pending cam locking design, the Bully pop-up tie down clamps under the truck bed side rails quickly and securely. It's constructed of stainless steel for durability and strength and mounts flush into the stake pocket. Plus, it keeps the painted surface of your truck protected with 38" neoprene rubber. And this comes in a 2 pk. to give you a total of four hooks with finger friendly tightening bolts. These hooks fit virtually all truck rails and allows easy no-drill installation.
