This vented backing plate is a performance upgrade to your Griot's Garage Random Orbital. It's a win-win as Griot's Garage exclusive heat management system with vertical and horizontal cooling ports delivers smoother operation, longer pad life, and better results. The plate features high-density urethane foam with chamfered edges for flexibility and improved contouring around body panels. The plate has rotational speed markings for optimum pad speed control.
Note: Fits recent model Griot's Garage 6" Random Orbitals (p/n 10750, 10765, or 10813), and random orbital/dual-action tools that accept a 5/16" - 24 threaded shaft. It is not compatible with the four-screw mounting system on the original Griot's Garage Random Orbital (p/n 10925).
