
On some wheelchairs, there may be an uneven seam along the back posts where a smaller
diameter tube is inserted into a larger diameter tube. If the cane clamps must be mounted over
this seam, the plastic inserts may be cut in half to allow the clamp to fasten securely onto the back
posts (see image B).
For wheelchairs with short back canes, it may be necessary to install Matrx PB Cane
Replacements (PBCR’s). The PBCR’s are designed to replace existing push handles or cane
extensions
on standard 1” (25 mm) back posts. The cane clamps can be mounted directly
onto the replacement back canes in order to allow proper installation of the Matrx PB. Cane
replacements are available from Motion Concepts (part# TRX2810).

*3/4” (19 mm) inserts are available from
Motion Concepts upon request.
