The BT7884 is the ideal solution for fixing AV accessories such as power supplies, media players and video conferencing equipment to any solution that uses a BT8390 Mounting Rail - such as Mode-AL and System X stands. Equipment is easily fitted to the removable plate and simply attached onto the tray. A tool-less release lever and assisted soft open/close system allows the tray to smoothly swing between the open and closed positions, giving user access to the fitted equipment.
