Manufactured from expanded polyurethane, it is particularly resistant to mechanical stresses and together with the BigFoot foam polishing pad reduces vibration to a minimum. The special perforations in this backing plate are designed to create an air flow that helps dissipate any heat generated by polishing. The Velcro on the backing provides an effective anchor for the foam polishing pad.

The Rupes 125 mm (5 inch) Backing Plate is a genuine factory replacement for the backing plate included with the Rupes LHR15 Mark II Big Foot Random Orbital Polisher. This backing plate is designed specifically for this polisher and is not compatible with other dual action polishers.
