BT8390 horizontal mounting rails are the central component of any System X installation, whether for a complex multi-screen setup or a single screen application. Made from aluminum, the rail is sturdy yet lightweight and is designed to support a variety of interface arms and mounts, allowing screens and other AV equipment to be fitted to the rail. Available in a range of lengths, the BT8390 can be mounted onto walls, poles, or System X support columns using different fixing kits (available separately). Rails can be cut to shorter lengths as required or joined together using extension kits (also available separately) for longer installations.
