3.4 Installing the Matrx PB
Installing the Mounting Plates
WARNING
The installation hardware provided is
high strength and tested for durability.
DO NOT substitute hardware. Use
only the hardware supplied.
1. Remove existing wheelchair back upholstery (if
applicable).
2. Establish the desired mounting plate set-
up/configuration for the user. Refer to Before
Installation on page 5.
3. Loosen cane clamp screws (x3) and loosely install
the cane clamp (with mounting bracket) onto
each back post. (Install plastic inserts if required).
4. Starting on one side, position the cane clamp at
the desired height on the back post and tighten
the clamp screws enough to hold it in place.
Clamps and set screws will be fully tightened after
the back is installed and all final adjustments have
been made.
5. From a fixed point on the wheelchair (e.g. seat
frame) measure the exact height of the installed
cane clamp assembly, and install the second cane
clamp at the same height on the opposite back
post - see image A. Ensure the cane
clamps/mounting plates are mounted parallel with
each other.
 Additional upper and lower adjustment
slots are provided on the mounting
plate to allow alternate mounting
heights if obstacles are encountered.
Using these alternate mounting slots will
increase or decrease the back height by
7/8" (22
mm
limit the range of available depth and/or
recline angle adjustment.
6. To install the Matrx PB onto the mounting plates:
A. Slide the lower mounting pins into the
hooked slots at the bottom of each
mounting plate (see image B).
B. With the lower pins in place, lock/snap
the upper mounting pins into the latch
mechanism at the top of the mounting
plates.
