Designed to increase the VESA mounting pattern of smaller mounts to accommodate larger screens, the BT7565 allows VESA 400 fixings to be increased to VESA 800. These adaptor arms are ultra-slim to keep the depth of the install to a minimum and can be used with a large variety of existing B-Tech products, such as the BT8310, BT8311 and System X interface arms. All mounting hardware included.
