Every Therafin tray bracket, clamp and slide needs the right fasteners behind it, and this hardware kit supplies the matched set for Z tray slide brackets. It is the part you order when a tray is being refitted to a different chair, when hardware has been lost in transit, or when a bracket has been reused and the original bolts no longer hold.
Having the correct kit on hand keeps a tray fitting predictable. The fasteners match the thread and length the bracket was designed around, so the tray sits square on the armrests and stays where it was set without working loose. For a therapist assembling a seating system, that removes a common source of delay.
