The Loadlok Kargo Keepers are designed for cargo shoring without using cargo restraint track. The ratchet mechanism expands the Kargo Keeper, clamping itself between and directly onto the trailer walls or floor and roof. Its large pressure absorbent feet grip firmly whilst also distribu ting the load. The spring loaded end  can compensate for an amount of flexing that might occur in some trailer walls. The tube is made from high quality aluminium.
