4.3 INSTALLING THE DOCKING TUBE
Begin by making a trial installation of the docking tube to determine its correct orientation and length
(during this trial installation, do not fully tighten the mounting nuts or bolts). To do this, you may either
place the wheelchair on a bench or table or remove the seat canvas to gain access to the underside of the
chair.
The rear of the docking tube has an L-shaped angle plate that is drilled and tapped to accept four
mounting bolts. This angle plate will sit on top of either your wheelchair’s camber bar or the rear crossbar.
Depending on your wheelchair geometry, this angle plate may either be oriented facing up (i.e., in an “L”
shape) or down (i.e., in an inverted “L” shape), but the plate must always sit on top of the bar and never
below it.
The front of the docking tube fixes to the bar underneath the seat via the steel band and the two black
hanging clamps attached to the docking tube. Loosening the two hanging clamps can alter the angle of
the docking tube and sliding the PVC coated steel band backwards or forwards. Depending on how steep
the angle of the docking tube is set will determine how far off the ground the front casters of the
wheelchair will be.
