Pronto shown. Check first to see if there are alternatives to these suggestions. Are there tubes with holes or screws that go into the seat pan to attach to? If not, there are two possibilities described.
Approach 1 involves attaching Collar clamps to the seat post. Approach 2 involves modifying an Adapter Plate to attach to the seat post using the 10 mm holes.

Offset options

Offsets attach to the wheelchair attachment hardware, and are used to:

  • Get around obstacles such as trays, brakes, footrests and armrests
  • Position the Wheelchair Bracket so the post is in the optimal position (post can be inserted and removed, brakes are unobstructed, footrests removed, accommodate the tray, etc)
  • Adjust the angle of the hardware and/or bracket to make sure the post is vertical

These plates can all be used to offset. To figure out which offset plate will work for you, see our Offset Guide.

How to mount: 

Attach an Adapter Plate 4 with custom 10 mm holes to the seat post. Attach the Post Extension Kit to AP4. If needed, use an Adapter Plate 2 and another L-Angle extension plate to offset the Wheelchair Bracket.
