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: 

Use two  1" Collar Clamps and an Adapter Plate 2 to create a bridge, or to attach on the horizontal seat tube. Use an L-Angle Extension plate or Angle Adjustment plate if necessary. Collar clamps can clamp tighter, because they go around the entire tube instead of partially, like the Round Clamp.   ***the bolt that comes with the WC-AP4 does go through the holes in the horizontal tube.  If you want to attach to these holes they will need to be drilled out to a larger size.
