The Rupes 6 Inch Backing Plate is the factory replacement for Rupes Skorpio RH 156A 6 Inch Pneumatic Random Orbital Palm Sanders. It is identical in design to the original and attaches with a hex bolt. The Rupes 6 Inch Backing Plate also fits Rupes LHR 21ES BigFoot Orbital Polishers.
Like all parts of the Rupes BigFoot System, the Rupes 6 Inch Backing Plate is highly engineered. It features a flexible design to allow your sanding disc and/or polishing pad to contour to curved body panels evenly. Drilled holes provide ventilation for sanding debris or polishing dust, carrying the offending contamination off of the painted surface.
As a replacement for the BigFoot Polishers, this backing plate has a less aggressive hook and look (Velcro-like) attachment material, making pad changes extremely fast and promoting longer life.
