Replacing 3" X 4" Pad Supports for 3" X 4" SurfPrep Sander 

SurfPrep sanders all are equipped with 'wearable' OEM parts that can be replaced. The 3" X 4" sander (air & electric) have Pad Supports that will wear down and potentially break over time. When this happens you can replace them to get your sander back and running.
Make sure to always replace both Pad Supports.
