The APS 15mm Backing Plate utilizes a spindle, much like the polishing cones. This attaches via the FVA50 for use with FLEX PXE80 or the RVA50 for use with RUPES iBrid.
Being 15mm, this plate will help with the smallest areas you'll encounter that need attention in your polishing work.
This may also attach to a 'bending shaft' accessory with the appropriate interface. Accessory must be able to tighten down on the shaft, NOT for use with the FLEX FS-140in this case.
*FVA50 Extension, Pads, and FLEX PXE80 are shown for use reference but not included
