Our 951 U Reinforcing Plate is designed specifically to bring extra security and stability to the hinges on hollow metal and aluminum frames. Best to help decrease sagging for heavy usage commercial doors or heavy duty storefront doors. With a silver metallic finish, these reinforcement plates are made from high quality materials to support your commercial entrance. Plates are intended to be used as a backing plate for 4½” standard butt hinges on most doors. These are sold individually but each door is recommended to have at least two backing plates to support their commercial door.
