Installing Quad Mount
The Back Support shell should be able to freely move between
the wheelchair canes, with approximately 0.5” (12mm) of clear-
ance between the cane and pins on each side.
The nal adjustments should be made later during the set-up.
Apply enough tension to the fasteners to prevent the brackets
from moving freely during the set-up, and use a coarse ad-
justment to achieve the intended desired height of the Back
Support.
Tools required: 4mm, 5mm Hex (Allen) Key
Note: The upper and lower pins that connect the Back
Support to the wheelchair canes have distinct dier-
ences. These must always be set in the right method:
A. Lower pin (with at edges on shank)
B. Upper pin (with round shank)
If a custom sized Back Support has been ordered, it
may not have the slots present. If so, mount the hard-
ware in the second row of holes from the outer edge.

Lightly attach all clamps to the wheelchair frame so they
can be raised or lowered but not so loosely they fall to
the bottom of the wheelchair frame.
