DO NOT modify cane clamps to fit 3/4-
inch tubing. Clamps provided are for 1-
inch or 7/8-inch tubing ONLY.
NOTE: The final positions of the upper (swivel) and lower

made to the Infinity Back to fit the wheelchair and user.
1. Remove existing back upholstery. Refer to wheelchair
owner's manual.
2. Loosen, but do not remove the mounting screw on
the cane clamp with allen wrench provided.
3. Perform one (1) of the following:
UPPER (SWIVEL) CLAMPS - Visually inspect the
clamps to determine whether they are for the RIGHT
or LEFT back cane as shown in FIGURE 1.
NOTE: The upper (swivel) cane clamps are marked
with R for RIGHT and L for LEFT.
NOTE: RIGHT and LEFT are determined by sitting
in the wheelchair.
LOWER (FIXED) CLAMPS - Proceed to STEP 4.
4. Hold the Infinity Back up to the back canes of the wheel-
chair at the desired mounting height.
5. Visually inspect the location of the mounting pins on
the Infinity Back to determine the proper positions for
each cane clamp.
6. Position the clamp on the back cane at the desired
height so that the open end of the clamp is facing the
REAR of the back cane as shown in FIGURE 1.
7. Torque mounting screw to 45-50 in./lbs.
8. Perform one (1) of the following:
A. If cane clamp holds desired mounting position,
proceed to STEP 9.
