Parts Included:
1 - Complete Radius Back
®
Assembly
1 - 5mm Hex Key
1 - 2.5mm Hex Key
1 - 5/32 in. Hex Key
1 - 1/8 in. Hex Key
Loosen the two clamp bolts (A) on both sides using the 5mm Hex Key. Tighten the clamps onto the left and
right wheelchair canes.
Gently loosen bolts (I) and (J) on both sides to allow for adjustment of all mounting brackets using the
1/8 in. Hex Key.
The mounting brackets adjust in and out to accommodate varying sized wheelchairs. The Radius-Back
®
can fit onto a
wheelchair 1" narrower to 1" wider of the purchased size.
Tip: Make sure the clamps are the same height relative to one another on the canes.
Tip: Make sure the clamps sit square to the wheelchair.
Note: The quick release levers may be tight when first actuated, but will loosen after 1-3 times.
If the backrest was able to be removed and reinstalled smoothly, no additional height adjustments are
needed. If further adjustments are needed, repeat step 5. Fully tighten bolts (B) when adjustments are
complete using the 5/32 in. Hex Key.

canes are relaxed.

Angle and Depth Adjustment: Loosen the two bolts (D) on both sides using the 5mm Hex Key. The back-
rest can be slid forward/backwards, and can also be rotated angularly. Tighten all four bolts when the
backrest depth and angle are adjusted.
7
Tighten set screw (E) on both sides using the supplied 2.5mm Hex Key to lock angle rotation. These set
screws intersect with the top bolts and prevents angle rotation.
8
Tighten set screw (F) on both sides using the 2.5mm Hex Key to prevent vertical movement and angular
rotation of the clamps.
9
Attach the cane mounts (G) facing forward as shown at the desired height, keeping each cane mount
symmetrical. To attach the cane mount, remove one side screw securing the metal strap, wrap the strap
around the cane, tighten both side strap bolts, and tighten the rear screw to secure.
10
Place the mounting peg (G) into the groove on the cane mount (H) on both sides.
5
The installation of the backrest is complete. Now make adjustments for depth, angle, and
height. The user can be seated during this process.
To adjust the height of the back, burn new holes into the back cover, lining up with the desired holes in
the wood insert. The bolts (B) can be inserted into the adjusted height setting. Keep the height on both
the left and right assembly symmetrical.
When the upper mounting brackets appear to be in line, finger-tighten bolts (B) on both sides, open quick
release levers (C), and remove/reinstall the backrest.
IMPORTANT: When installation and adjustments are complete, all bolts should be tightened
to a minimum of 85 in-lbs.
*This does not include set screws.

When hardware is properly placed, be sure to secure bolts (I) and (J) tightly on both sides.
