981.321N | Rupes 6" Velcro Backing Plate.
Rupes BigFoot Random Orbital Polishers are robust, well-built machines. Even the factory installed backing plate can last for years. But, accidents do happen. Should the backing plate sustain damage due to an inadvertent dropping of the machine or some other unforseen event, you'll be dead in the water unless you've got a replacement on hand. The Rupes 981.321N is a factory-direct replacement for the following 6" machines:
LHR21ES | LHR21II | LHR21III
This backing plate will also physically mount onto the following 5" machines:
LHR15ES | LHR15II | LHR15III | LHR12E
Note: The 981.321N 6" backing plate is 5 grams heavier than the Rupes 980.027N 5" backing plate (130g vs 125g). Although installing this plate onto machines originally designed for 5-inch plates will enable the use of 6-inch pads & discs, machine vibration & balance may be negatively affected.

Hook face, compatible with all hook & loop systems.
One of our best sellers, and for good reason! For starters, this plate features more flexibility than its vinyl backed counterpart (Mirka #106).
The medium density polyurethane foam used as the core of this plate is firm enough to level substrates, but thanks to its flared edge, conformability is good when used on curved surfaces.
Mirka's backing plates are manufactured using a top quality molded polymer construction. This means that the black hub, yellow foam center, and white face are molded together, not glued.
Each plate is balanced to eliminate vibration, so you can work comfortably.
