3. Reposition the camber tube mounts to the desired
height—making sure to choose a height that will
permit you to reattach the camber tube mounts to
the camber mount brackets using all four Allen
Screws on each side. Generally, there will be
approximately 1-1/2" up or down adjustability, but
the precise amount depends on the original
dimensions of the chair you ordered.
4. Align the holes of the camber tube mounts and
camber mount brackets.
5. On each side of the chair, reinstall the four Allen
Screws and locknuts and securely tighten all eight
screws.
6. Check the toe-in/toe-out and adjust as needed, and
square the front casters as needed.

1. Loosen, but do not remove, the four (two on each
side) Allen Screws that secure the toe clamps and
the camber mount brackets to the frame. See
Figure 63.
2. Slide the entire camber tube mounting assembly
forward or rearward along the frame until it is
positioned in the desired location. Use a ruler to
ensure the assembly on both sides of the chair are
the same distance from the ends of the frame tubes.
3. Securely tighten the four (two on each side) Allen
Screws that secure the toe clamps and camber
mount brackets to the frame.
4. Check the rear seat height and adjust as needed.
5. Check the toe-in/toe-out and adjust as needed and
square the front casters as needed.
Note: The toe clamp/camber mount bracket axle
assembly cannot be positioned further rearward than
the position of the Allen Screw securing the backrest
bracket to the frame. However, the rearward toe
clamps have a hole to permit you to position this
rearward toe clamp in line with the backrest bracket.
Each ZRA and Aero Z wheelchair is shipped with a
pair of longer Allen Screws and spare washers to
permit you to make this adjustment.
