This 3" (75mm) diameter backing plate was made specifically for use with the Rupes LHR75 (pneumatic) and LHR75e (electric) BigFoot Random Orbital Polishers. It's a good idea to keep at least one spare on hand, as they are not all that easy to locate in a pinch.

Occasionally, BigFoot® needs a new shoe.

The Rupes LHR75 BigFoot 3" Air-Powered Mini Random Orbital Polisher is one wicked machine.  Its massive 15mm ø orbit and 11,000 RPM top-speed can stress the backing plate's Velcro® hooks, causing them to break.

Technique, overall use, and the type of work being accomplished can also impact the life of the plate. Should you accidentally drop the machine (and the plate is impacted in the fall), its thin metal mounting pad can bend, causing the plate to wobble something fierce.

Eventually, in one way or another... the backing plate will need to be replaced.

The Rupes 990.007 is a direct repacement for the factory installed unit.  It's a good idea to keep at least one spare on hand if you own an LHR75, as they are not all that easy to locate in a pinch.

A chunky bruiser of a plate. Now an all-time favorite!

This backing plate is built like a tank. Its height comes in handy at times, while the added weight allows it to work well with machines designed for 5" and 6" backing plates.

Molded polymer construction means that the black hub, yellow foam center, and white face are molded together, not glued. Consequently, durability is tip-top.

The face of the plate is stiff, yet when used on curved surfaces its edge conforms to some degree.  The hook material is short, grabby, and long lasting.  Should the side of the plate happen to contact a delicate object, you'll be relieved to know that it is soft to the touch.

This is great addition to your backing plate arsenal.

Hook face, compatible with all hook & loop systems.

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.

The medium density polyurethane foam is somewhat firm, but will give a small degree due to its flared edge.

This backing plate is the same diameter as the ever-popular DMC3 / DMF3 Meguiar's 3" DA Microfiber Discs. By delivering full support to the outer edge, it can increase cutting power immensely (best guess, 30%), yet deliver a more refined finish than the standard undersized Meguiar's recommended backing plate S3BP.
