The “Power Plate” Backer is the industries best backer! This innovative shape provides great stud support and is almost unbendable. We added a radial lobe to a standard 1.125” backer by reducing wear and tear on the track and increasing stud rigidity. By decreasing the weakest flat corner area of the square backer we have reduced unnecessary weight and bending of the corners for a super strong design. Light-weight and durable, use the “Power Plate” aluminum backer and receive the best benefits of both square and round backers in one design!
