System X Wall Tie-BackThe BT8380-WTB is a tie-back system that provides added stability to B-Tech installations. Compatible with System X vertical columns, the BT8350 range of videowall stands and System 2 poles, the BT8380-WTB works by securing the installation to an adjoining wall. A tie-back may be required for extra tall installations or set-ups using small floor bases such as the BT8380-FFB or the BT8380-SHB. The BT8380-WTB features an adjustable extension which allows installations to be mounted from 214mm up to 707mm from the wall.
