Hardware (2 Point) - Figure A
1
Loosen the two clamp bolts (A) on both sides using the 5mm Hex Key. Place and then tighten the clamps onto the
wheelchair canes.
Note: Make sure the clamps are the same height relative to one another on the canes and they sit square to the wheelchair. Make
sure cane clamp locking screws (J) are flush to the inner clamp surface prior to installation.
2
Slightly loosen the bolts (B) on both of the sides using the 5mm Hex Key. Slide the brackets in and out until the
wheelchair canes are relaxed. If further adjustments are needed that the bracket cannot accommodate, follow step
2A for Quick Release or 2B for Fixed Compass.
2A
Quick Release - Release toggle (C) and adjust the clamp angles until the wheelchair canes are relaxed. Then lower the
toggle to engage the locking mechanism.
2B
Fixed - Loosen (but do not remove) the bolts (D) with the 5mm Hex Key and an 11mm Open-End Wrench around cone
(E). Adjust the clamp angles until the wheelchair canes are relaxed.
3
Once the hardware is at the correct position with the wheelchair canes relaxed, fully tighten the bolts (B) on both of
the sides. If the bolts (D) were loosened in step 2B, tighten the bolts (D) with the 5mm Hex Key and an 11mm Open-
End Wrench around cone (E) between 90-110in-lbs.
Note: The installation of the back support is complete. Adjustments can now be made with the user seated during the process.
4
If additional height adjustment is needed, lightly lossen either the bolts (A) or (B) on both of the sides using the 5mm
Hex Key. The back support can slide up and down using either the slot on the back support shell or on the canes.
Tighten all four of the bolts (A) or (B) again once at the desired height.
5
Depth: Loosen the bolt (F) on both sides using the 5mm Hex Key. The back support can slide forward or backwards up
to 2 inches total. Tighten both of the bolts (F) after the back support depth is adjusted.
Note: If additional depth adjustment is needed, Compass can be used in alternate configurations including swapping just the cane
clamp or the whole depth adjustment bracket with cane clamp assembly to the opposite side of the wheelchair. See figure C for
example.
6
Recline: Loosen the top and bottom bolts (G) on both sides using th 5mm Hex Key so the back support can be tilted.
Tighten all four bolts (G) after the back support angle is adjusted.
When installation and adjustments are complete, all bolts should be tightened to a minimum of 85in-lbs.
(This does not include locking screws (H) and (J). TIghten these only until contact is made.)
7
Tighten locking screws (H) on both sides using the 3mm Hex Key to lock angle rotation. These make contact with the
recline bolts (G) and prevent angle rotation but may also be used for minor angle adjustments if the bolts (G) are
loose. Overtightening of (H) may cause unwanted changes in recline position.
8
Tighten the cane clamp lockign screw (J) on both sides using the 3mm Hex Key. This makes contact with the
wheelchair canes to lock in the final clamp position.

Hardware (4 Point) - Figure B
Note: If the alternate Compass 2 Point configuration was used above, 4 Point hardware may need to be reconfigured as well.
1
Gently loosen the bolts (K) and (L) on both sides to allow for adjustment of all mounting brackets using the 4mm Hex
Key.
2
Adjust the hardware so that the mounting pegs (M) are resting agaisnt the canes as shown. Tighten the bolts (K) and
(L) to set the placement of the hardware.
3
Attatch the cane mounts to secure each mounting peg against the cane. Remove screw (P) using 1/8” Hex Key to
release one side of the cane strap (R) and remove from the cane mount (N).
Note: Use the short strap (pre-attached) as is for 7/8” and 1” canes. Use inner strap holes on the shorter strap for 3/4” canes or
replace the strap and use the longer strap provided in kit for 1 1/8” abd 1 1/4” diameter canes.
4
Place the cane mounts (N) just below the mounting pegs (M) and wrap strap (R) around the cane. Replace the screw
(P) and tighten. Complete for both the left and the right sides.
5
Tighten the screws located on the front of the cane mounts (not pictured) to fully secure the strap.
