3"X 4" MEDIUM DENSITY (YELLOW) INTERFACE PAD. VAC HOLES

Interface pads easily contour the sander and sanding sheets to surfaces. Perfect for sanding molding cabinetry, and more. We recommend using a J-Hook Backup Pad when sanding with any Interface Pads. This is because the interface pad will not stay in place while sanding using a standard Hook and Loop backup pad, whereas using a J-Hook backup pad will allow the interface pad to stay in place.
