Used on top of your regular Clean Sanding pad on 3M's 3" x 4" Random Orbital Vacuum Sanders when extra soft, conformability is desired.
These pads ad an extra cushion under the sandpaper allowing it to maintain better contact on contoured surfaces like boat hulls or furniture.
The durable foam allows the operator to sand into corners without damaging the work piece.
Can be used on central vacuum or self-generating vacuum sanders
The 33 holes in the Interface Pad match the 33 holes in the Hookit Clean Sanding Backup Pads such as #20435
