As part of the installation process, you will attach the mounting clamps onto your wheelchair. The wheelchair attachment fit most wheelchairs.

However, a few wheelchairs will not fit our clamps. Use the following guide to determine whether or not your wheelchair is compatible with our wheelchair attachment.


1. Seat width must be between 14 to 22 in -or- 35.5 to 55.8 cm (measured end-to-end on the width of your seat cushion).

2. Tube diameters. Currently, supported tubing diameters are:

7/8 in -or- 22.2 mm | 1 in -or- 25.4 mm | 1.125 in -or- 28.6 mm | 1.2 in -or- 30.5 mm | 1.25 in -or- 31.8 mm


3. Tube clearance. To attach the clamps, 1.25 in -or- 32 mm clearance is required. Diagrams with examples of tube clearances are given in the images below.

4. Tube angle. Ideally, the tubes should be vertical or close to vertical. However, installation is possible with tubes that taper inwards with slight angles. The larger the taper angle the more challenging it is to use our “Quick Release Coupler” attachment. See the diagrams on the following pages where illustrations of wheelchair designs with tapering tube angles are shown.

5. Footrests on folding chairs. Removable footrests can pose challenges for our clamp installation, so please consult Page 3 in the Fitting Guide where examples of wheelchair designs with removable footrests are given. Never mount our clamps directly onto removable footrests as they were not designed to take such riding forces.
