BigFoot's dance moves can be tough on shoes.

The Rupes LHR 21ES is quite a tool.  It delivers a 21mm ø orbit, and tops out at 4,200 RPM.  Knowing this, it's no big surprise that eventually you'll need to replace its backing plate.  Over time, the backing plate's attachment hooks can degrade or break away, causing pads and discs to fling from the machine during use!  

Surprisingly, the primary reason backing plates need to be changed is not due to wear.  The fact is, nothing can relegate a backing plate to the trash bin faster than an accidental dropping of the machine.  

Regardless of how it happens, if the machine takes a fall and crashes to the ground, there's a very high likelihood that the mounting pad (essentially a stamped steel washer) will bend.  If this happens, you'll be dead in the water unless you've got a backup plate on hand.

This backing plate is the genuine article!  A direct replacement Rupes® 981.321 150mm Backing Plate, made specifically for use with the Rupes® LHR 21ES BigFoot Random Orbital Polisher.  Also fits the LHR 15ES, allowing the machine to be outfitted with 6" (150mm) pads and discs.

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.

A perfect mate for Meguiar's® Soft Buff 2.0 Pads.

Leave it to Meguiar's to design a backing plate that perfectly fits their buffing pads. This unique system approach allows Meguiar's to squeeze every bit of capability from their hardware.

This backing plate will increase buffing pad performance and durability, optimizing polishing performance in the process. What's the big deal, you ask? A lot!

For starters, the outer edge of the plate has been designed to help minimize pad hazing. Plate thickness is varied, which allows the buffing pad to better contour to complex surfaces.

The specialized low profile Velcro® attachment material secures the pad to the plate, gently yet powerfully locking it in place until the job is done.  Sweating the small details pays off, as a light pull of the pad easily releases it. The attachment material has been purposely eliminated along the outer edge of the face. This seemingly small detail increases flexibility of the pad, but more importantly eliminates "edge-digging", which often occurs when the hook material "cuts" into the back of the buffing pad.

Finally, the center of the face has been cut from the plate, eliminating edge digging at the center of the pad, dropping temperature buildup in the process. It's an extra step that is seemingly insignificant, but longevity of the buffing pad is increased.  Thanks Meguiar's!

"Failure is not an option!"
Durability is superb, thanks to its one-piece molded design.

The medium density polyurethane foam used as the core of this plate is firm enough to level substrates, but will give a small degree.

It does not have a sharply flared edge, so it has less give than its hook-backed counterpart (Mirka #106GG). The added edge height means this plate can take quite a beating.

My new favorite rotary plate!  The WRSBP Soft Buff 6" Rotary SOFT Backing Plate offers up plenty of support for 6", 7", and 8" diameter buffing pads. Designed to minimize the potential for pad-induced swirl marks, it is remarkably comfortable to use. Cushiony material allows the buffing pad to conform easily to flat or curved surfaces, thus minimizing the potential for grabiness of the pad, pad hop, and pad chatter.

The WRSBP's molded design is virtually indestructible, while its micro-hook face attaches strongly to pretty much all Velcro-style buffing pads (yet pad removal remains a breeze).

Pair with Meguiar's Rotary Foam Pads, or Meguiar's super low profile DA Foam Discs.

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.

As before, it features a pad alignment plug (located at the center of the face), making it a snap to align buffing pads that utilize a centering hole.

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.

This backing plate was originally introduced as an integral part of the Meguiar's So1o™ One Liquid System, but it performs incredibly well when paired with the majority of foam or wool buffing pads available today.

While it can be difficult to find the proper balance between flexibility and firmness, this plate hits the mark.  Credit must go to the carefully shaped, engineered foam center. 

In addition, the specialized foam has been optimized to minimize the potential for pad-induced swirl marks.

Note:
For maximum performance, pair with any of the So1o™ wool or foam buffing pads.  With a quartet to choose from, you're certain to find the right combination!
