1. Wheelchair Requirements
As part of our installation process, you will attach our mounting clamps onto your
wheelchair.
Our wheelchair attachments fit most wheelchairs. However, a few wheelchairs will not fit
our clamps. Use this guide to determine if our devices are right for you.
There are five points that must be considered in order to determine whether your
wheelchair is compatible with our wheelchair attachments:
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:
(printable tubing ruler on next page).
• 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
If your tubing is a different shape or diameter contact sales@riomobility.com
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 following pages.
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 below 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.
