Designed to ceiling mount screens up to 50kg in either landscape or portrait orientation, the BT8424 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°. Leveling screws are included on the interface arms to finely adjust the screen height, and locking screws help prevent unauthorized removal of the screen. Cover plates are supplied for a neat and tidy installation.
