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.

One of our best sellers, and for good reason! For starters, this plate features more flexibility than its vinyl backed counterpart (Mirka #106).

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.

It looks stealth, but you'll surely notice the quality.

Meguiar's has made this model of backing plate for many years, but this is an all-new design. Durability is top notch, thanks to its sturdy one-piece molded construction.

The face of the plate is firm with a minute amount of cushioning, virtually guaranteeing a smooth feel while polishing.

The outer edge has been finessed to allow increased contourability of the pad when used on complex surfaces, or for those times when the pad must be tilted on edge for targeted buffing.
