A backstrap runs behind the wheelchair backrest and holds a full tray in place, so the tray cannot be pushed forward off its brackets. It is a simple part that answers a real safety question on a tray that a client leans on.
For clients who use the tray as a working surface, or who push through their arms to reposition, the strap takes the forward load that would otherwise sit on the front fixings alone. For carers, it makes the tray predictable: it stays put until someone undoes the strap.
This is the Therafin strap made for their full tray range and fits as a replacement for a worn or missing original.
