6 in. Stick-On Backup Pad

6" backing pad for stick on sandpaper discs. Designed for use with all 6 in. PSA (stickit) backed sanding discs. A medium density pad that is more durable than the fine finishing pads. These pads are 3/4 in. thick and have a 5/16 in. x 24 threaded shank for all dual action sanders. Firm enough for flat surfaces, yet soft enough for curved surfaces.
