3.0 - Before Installation- Important!
Mounting Plate Configurations:
SEAT DEPTH (Fore/Aft Adjustment):
The Cane Clamp Kits may be mounted in a forward or rearward position on the back
canes. The cane clamp assemblies are shipped in the rearward mounting configura-
tion- see Figure 2A below. This maximizes the seat depth on the wheelchair seat (up
to 2.5" (64 ) maximum rearward offset).
mm
By inverting the cane clamps on the back canes, the assembly can be reconfigured to
give a more forward mounting position* (up to a maximum 2.5" (64
see Figure 2B below).
*note: in the forward position, the mounting plates must also be removed and reinstalled in the
proper orientation - as indicated below.
The slots in the upper and lower mounting plates, also provide up to 1.5" (38
fore and aft adjustment relative to the cane clamp.
P L E A S E N O T E
When establishing the mounting position for the MaTRx back, ensure the stability of
the wheelchair is not compromised.
Adjusting the fore and aft position of the backrest will alter the user's center of grav-
ity within the wheelchair. A recessed back position can significantly reduce the
rearward stability of the wheelchair. Similarly, a more forward back position will re-
duce the wheelchair's forward stability.
