Pronto

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: 

Use two collar clamps to attach to the seat post. Post measures 180mm; 2.25" inside diameter should work. Bridge the two collar clamps with an Adapter Plate 4. Attach a Post Extension Kit to the AP4. Possible use of an Adapter Plate 2 and/or L-Angle extension plate to offset the Wheelchair Bracket forward of the armrests.

Installation support: 

Suggested extra parts

Other hardware: 

A set of two 2.25" (180mm) inner diameter collar clamps. Order a set of Custom collar clamps or do-it-yourself.
Customize: Drill and tap a hole in each set. We typically use 1/4-28 bolts, but if metric screws are more available, M6 bolts and tapping will work. Either bolt size will attach the Adapter Plate to the collar clamps through the smaller holes and slots.

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.

Suggested extra parts

Other hardware: 

Customize Adapter Plate 4, drilling holes for 10 mm post holes. Attach Post Extension Kit to AP4.

Bolts and nuts: two sets of 10 mm bolts and nuts to attach through the seat post holes.
