BigFoot's dance moves can be tough on shoes.
Rupes LHR15ES Legacy & LHR15ll Markll 5" Polishers are quite the pair.  They deliver a 15mm ø orbit, and top out at 4,800 & 5,300 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® 980.027 125mm Backing Plate, made specifically for use with the Rupes® LHR15ES & LHR15ll BigFoot Random Orbital Polishers.  Also fits the LHR21ES & LHR21ll, allowing the machine to be outfitted with 5" (125mm) pads and discs.
