You can rely on the MBK455 angled mounting bracket set* for an extra inclination of 90° for the ARES5A when needed. This 90° bracket makes it possible to mount the ARES5A set to a smartboard or trolley neatly concealing the bracket away. The MBK455 is also perfectly suited for mounting to various ceiling surfaces. *ARES5A not included with the MBK455 bracket system.
