Replace sling back upholstery on a wheelchair that has back canes
with integrated push handles but without existing threaded inserts
1. Verify that the Corbac will be used without the wheelchair back upholstery and that
the rear canes are equipped with push handles but without existing threaded inserts
(Illustration 3).
2. Determine the cane diameter at the location where the top of the Corbac height will be
positioned.
3. Use the following clamps for your cane diameter:
1" cane ............. Large clamps without shims
7/8" cane ............. Large clamps with shims
3/4" cane ............. Small clamps with shims
4. With the clamp’s screw inserts towards the back side of the wheelchair, install the
clamps by spreading the clamps over the canes (Illustration 4). Adjust the clamp height to
¾" below the final Corbac height and ensure both clamps are at the same height above
the seat rails (Illustration 5). Do not install the screws at this time.

pushing the handles through the holes provided in the inside upper and lateral corners
of the large pocket (Illustration 6).
c. Align the adjustable mount grommet holes with the clamps and insert the 10-32
screws provided. Adjust the clamp rotations to match the desired curvature of the
adjustable mount. Tighten the screws securely (Illustration 7).
6. Tighten straps lightly. On some rigid model wheelchairs, the bottom strap(s) may be
located below the rigidizer bar.
