3. Perform one of the following:
A. Non Suspension ‐ securely tighten the hex screw that secures one of the top clamps to the wheelchair frame.
B. Suspension ‐ securely tighten the two hex screws that secure one of the top clamps to the wheelchair frame.
NOTE: Securely tightening one socket screw at a time ensures that the camber clamps will sit flush on the wheelchair frame.
4. Repeat STEP 3 for the opposite side of the wheelchair.
NOTE: The distance between the front of the back post and the back of the top clamp on each side of the wheelchair can be measured as an
additional check to make sure the camber clamps sit flush on the wheelchair frame (the measurements should be the same) (DETAIL ʺAʺ).
5. Roll the wheelchair before using to make sure there is no excessive drag to either side.
NOTE: If drag to either side occurs, refer to Determining Toe In/Toe Out on page 28.

NEVER position the camber inserts in the axle tube with more than 3-inches (12 indexing marks
showing) of the camber insert outside of the axle tube. Otherwise, the camber inserts will not be
securely tightened in the axle tube resulting in possible injury to the user or damage to the
wheelchair.
