A strong plastic sheet with molded harpoon hooks is mechanically bonded to a HD pad driver block with a 1.5” riser. The hooks hold and drive a pad. Access holes in the hook sheet are positioned under the shower feed holes in the block, allowing scrub solution to feed through the pad driver onto the floor. Available in sizes: 11” thru 20”
