For multi-screen installations, the horizontal mounting rails BT8390 are the central element of any System X installation, whether for a complex multi-screen setup or a single display application. Made from aluminum, the rail is robust yet lightweight and is designed to support a variety of interface arms and mounts, allowing screens and other AV devices to be attached to the rail. The BT8390 is available in various lengths and can be mounted on walls, poles, or System X support columns using a range of different mounting kits. The rails can be cut to shorter lengths if needed or connected with extension kits for significantly longer installations.
