The BT7031 allows B-Tech AV accessory shelves to be fitted onto a B-Tech flat screen mount, making it the ideal solution for adding a VC camera or other accessible media above or below the screen. The adaptor arm can hook onto a range of B-Tech flat screen wall mounts or onto a BT8390 System X Rail and is suitable for use with a large range of screen sizes, featuring an adjustable extension arm that can be freely positioned anywhere along the mount. The BT7031 can also be used as a pair to mount larger shelves such as the BT7032.
