Bona Steel Plates are designed to offer a true hard-plating option during the sanding process, combining the traditional hard-plating technique with newer multi-directional sanding. Specifically created for contractors who rely on the flattest possible sanding systems for their customers, they help remove chatter and prevent dish-out on any surface. Steel Plates are available in 4 x 6” or 6 x 5” with Hook and Loop, to be used with the Bona Power Drive® or the Bona MultiDisc.
