3M Hookit Clean Sanding Multi-Connection Disc Pad is a replacement backup pad that provides a stronger, more reliable attachment for net, paper, and film backed abrasives to 6-inch dual-action sanders. Connects to 3M, Festool, and most other dual-action sanders. Use 3M Hookit Clean Sanding Multi-Connection Disc Pad as an accessory to enhance your sanding process. It features a longer, more-durable "J-hook style" hook-and-loop attachment that provides a good hold on net, paper and film-backed abrasives. The pad’s multi-hole face helps reduce the need for hole alignment.
