BT8390 horizontal mounting rails are the central component of any System X installation whether it be for a complex multi-screen install or a single screen application. Made from aluminium the rail itself 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 a range of different fixing kits (available separately). Rails can be cut to shorter lengths as required or joined together using extension kits (also available separately) for much longer installs.
