The newest lock we offer, which we also manufacture, is the Step Loc. It’s used in our trailer and van roller bed systems. We named it the Step Loc because you install and release it with your foot. It attaches to steel pins in a ladder tray that’s secured to the floor of the trailer or van. Containers, pallets and bulk freight can be locked in one-inch increments from the rear door to the nose of the trailer (including refrigerated trailers). For vans, one or two locks are used at the rear of the vehicle. For trailers, the locks are used in two tracks, as needed, to retain the load. A cargo strap is used to retain any freight that needs to fit tight against the back door.
