ROP - Removable Outer Piece

The Removable Outer Piece is used with the Removable Frame Clamp Receiver.
The two components replace the standard outer piece and index clamp of
the Folding Mount and Rigid Mount to create the ROP Version used primarily
for wheelchairs with a tilting seat system. It can also be used in situations
where it is desired to lock the mount assembly onto the wheelchair.

The Removable Outer Piece is installed onto the vertical tube of the mount
assembly and provides positioning and height adjustment.
It allows the mount assembly to be attached to any location a Removable
Frame Clamp Receiver is installed.
