Sim-Lab Keyboard Tray Joint 40 Adapter

The Sim-Lab Keyboard Tray needs an adapter to fit onto sim rigs with angled uprights. New units come with the adapter, but older units do not. This is a clone of the keyboard adapter that comes with the keyboard tray. It can also be used with other 40 or 15 series aluminum profile joints to attach to 20-degree uprights on sim rigs for other purposes.
