Abstract
A concrete forming panel with lightweight siderail includes a face plate and a frame, the frame including at least one siderail and a bushing plate coupled thereto, the bushing plate having thereon a wear member of a material having greater hardness than the bushing plate. The wear member is positioned adjacent an opening in the bushing plate, the hole being in registry with a corresponding hole in the siderail, whereby fasteners passing through the hole and opening to couple the forming panel to other structural members in a concrete forming system, such as another forming panel, will engage the wear member. The use of a wear member permits the use of lighter weight siderails and bushing plates.
