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. Micro-hook Velcro.

The Mirka 102GG 3" Velcro 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 Velcro 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.  Its micro-hook Velcro 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.

Mirka 102GG specifications: 2-7/8" diameter | 5/16-24 male thread

Sanding? Add a Mirka Interface Pad.
Interface pads increase contourability and help to better distribute applied pressure across the face of the disc.  To achieve maximum cushioning and shapability of the sanding disc, this is the interface pad you'll need. The Mirka 1033 3" Velcro Interface Pad measures 3" in diameter, and is 1/2" tall. More info: 1033

Micro-hook Velcro is compatible with all hook & loop systems.

The Mirka 103GG 3-1/2" Velcro Backing Plate measures in at an actual 3-3/8" diameter, making it the same exact diameter as the ever-popular DMC3 / DMF3 Meguiar's 3" DA Microfiber Discs. By delivering full support to the outer edge of the microfiber disc, cutting power can increase immensely. It can also help to create a more refined finish versus using the Meguiar's recommended S3BP backing plate. By fully supporting the microfiber, random rotation of the plate runs at maximum potential.


Mirka's backing plates are manufactured using a top quality molded polymer construction. This means that the rigid inner  hub, yellow foam center, and Velcro 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.
