## Long description

The B-Tech BT8390 Angle Adjustment Connector (45° Rotation) in black is a single-piece mounting accessory designed for System X rails. It provides an adjustable connection between mounting rails with a range from -45° to +45°, enabling precise alignment of curved multi-screen installations such as videowalls and digital menu boards. With dimensions of 450 mm width, 78 mm depth and 93.8 mm height, the connector supports compact and efficient use of space while maintaining a stable, load-bearing joint. Integrated angle guides help to speed up installation and ensure repeatable, accurate angles when joining rails.
Advantages
The connector offers controlled angle adjustment between connected System X rails, allowing fine tuning from negative to positive 45 degrees without the need for custom machining. Its robust construction provides a stable joint suitable for multi-screen arrays, while the black finish helps the component remain visually discreet behind displays. The integrated angle guides simplify alignment and reduce installation time, and the single-piece design means fewer separate parts to manage on site.
Suitable for
 Curved videowalls and multi-screen displays
 Digital menu boards and retail signage
 Commercial AV installations requiring adjustable rail joins
 Projects where compact mounting components are needed to save space

How to use
Position the BT8390 connector between two System X rails at the intended joint and set the desired angle within the -45° to +45° range using the integrated guides. Secure the connector to each rail according to the rail manufacturer’s fastening method, ensuring all fasteners are tightened to the recommended torque. Verify alignment and stability of the rails and connected displays before completing any final cable management or powering equipment. For safety, follow standard AV installation practices and check that the assembled structure meets load-bearing requirements for the mounted screens.
Usage recommendations
Use the connector for fixed-angle joins where repeatable, accurate curvature is required; pre-configure the angle on a bench if multiple identical joints are needed to ensure uniform curvature across a videowall. Regularly inspect fasteners and alignment after initial installation and during routine maintenance.
