This 8 x 19-inch floor sanding belt is designed for extreme removal of old finishes and dimensional sanding to level high spots on your floor. It fits the Clarke EZ-8 (slide-on drum) floor sander. The bi-directional flush joint ensures smooth operation in either direction, while the advanced resin bonding system secures the grain to the cloth backing. The heavy-duty X-weight cloth resists tearing for durability.
