Labelmaster offers the King Pin Lock to secure truck transportation trailers and ocean containers and the cargo they contain. Made of solid-cast, ductile, cast-iron steel alloy, this single-component design is user-friendly, right down to the convenient carrying handle. It locks without a key, and the all-purpose carrying handle prevents accidental locking when stored in the ready-to-use position.
