Sanwa JLF-P1-S Mounting Plate

The SANWA JLF-P1-S mounting plate has curves for lower or higher placement of the mounting screws or bolts.  This makes bottom-mounting in a wood panel more viable as the joystick can be installed in a thicker panel. The S-plate is turned over so the joystick can be installed at a distance from a thin panel.  If you need to install the plate onto your JLF joystick, you can add the Sanwa JLF-SS-Kit to your order.
