Designed to ceiling mount two screens in a back-to-back configuration, the BT8428 is available in a choice of four different drop lengths; 1m, 1.5m, 2m and 3m. The mount uses B-Tech's unique 'Torsion-Tilt' mechanism for easy tilt up to +/-15°. Levelling screws are included on the interface arms to finely adjust the screen height and locking screws help prevent unauthorised removal of the screen.
