Replacement Dual Action Polisher PRO Backing Plate
This 6" (152 mm) polyurethane backing plate with a 5/16" (24) threaded post is a direct replacement for the Original Dual Action Polisher PRO.
Confirm that your polisher is OFF and UNPLUGGED. Using the wrench that was supplied with your polisher engage the backing plate nut and unscrew old backing plate. Reverse this process to screw on new backing plate.
