Installing the Mounting Hardware

 For ease of installation, install the mounting bracket
hardware onto the rigidizer bar first. The MX1 back
cushion can be installed onto the rigidizer bracket after
the mounting hardware is installed.
1. Remove any existing wheelchair back, back upholstery or back cane
hardware. Refer to the user manual that came with the wheelchair
or back upholstery.
2. Loosen the compression bar hardware A inside the rigidizer
bracket B.
WARNING
DO NOT adjust the center screw in the rigidizer
bracket. The center screw C is designed only to hold
the compression bar in place during installation.
Adjusting this screw may prevent the compression bar
from tightening properly onto the back cane.
 The compression bar hardware must be loosened to
ensure the rigidizer bracket rests flush against the rigidizer
bar D.
The rigidizer bar is shown in the illustration for reference
only.

 The rigidizer bracket is secured to the rigidizer bar via a
band clamp. Each hardware kit comes equipped with
one of three differently sized band clamps.

In order to optimize the available height adjustment on the

5. Align the edges of the clamp with the corresponding slots F in the
rigidizer bracket.
6. Carefully slide the rigidizer bracket onto the band clamp.

8. Insert the two locking pins G into the rigidizer bracket to hold the
band clamp in place.
