Rupes 6" Random Orbital Backing Plate
The Rupes® BigFoot series of 6" Random Orbital Polishers are impressive performers. They deliver a 21mm diameter orbit, and can generate massive momentum. Some models of the LHR21 top out at 4,500 orbits per minute! A stressful situation, for any backing plate.
After extended use, the factory installed backing plate can degrade.
An accidental dropping of the machine can bend or break the plate.
