These adaptor plates are the link between a Quantum TB3 track and the accessories you want to hang off it. They slide into the track and give you a fixed mounting surface for tray hardware, laptrays and other attachments without clamping anything to the armrest tube.
Because the plates use the chair’s own track, the position can be shifted along the length of the armrest during a fitting and adjusted again if the client’s reach or seating changes. Two lengths are offered so you can match the plate to the armrest you are working with.
They are supplied as a pair, which is what you need for a full tray.
