LWG 3” Metal Plates are used to mechanically attach insulation, cover boards and base sheets to lightweight insulating concrete (LWIC) and gypsum decks. The LWG 3” Metal Plate is a circular design with one center fastener placement hole and eight equally spaced fastener placement holes around the perimeter of the plate allowing for maximum versatility. Required pullout values can be achieved by installing multiple LWG Fasteners in one LWG 3” Metal Plate.
