Genuine OEM replacement part, this part is sold individually.
The 151281-09 Pad is used to hold 5 inch PSA (Pressure Sensitive Adhesive) sandpaper with 8 vacuum holes.
Applying too much pressure on the sander may cause premature wear on the pad.
When a pad needs to be replaced, simply remove the three screws that hold the pad to the sander, then replace it with a new pad.
