## Long description

Interface adapter arm B-TECH System X — Pop-Out, micro-adjustment, VESA 400, 50 kg, 12.6–30 cm is a single-display mounting interface for use on System X horizontal rails. Designed for medium to large screens up to 65", the arm features a VESA 400 mounting pattern, a pop-out mechanism for quick access during installation and maintenance, and tool-less 8-point micro-adjustment for precise alignment. The unit supports up to 50 kg and has an adjustable wall offset from 12.6 cm to 30 cm, finished in black for a discreet appearance in homes, offices and public spaces.
Advantages
The pop-out design allows installers to move the display forward for easy cable access and connections without complete disassembly. Tool-less 8-point micro-adjustment provides fine alignment in both portrait and landscape orientations, reducing installation time and the need for repeat adjustments. Compatibility with System X rails and universal video wall screens offers flexibility for single mounts or multi-screen video wall assemblies. The robust construction supports heavy displays while maintaining a low visible profile in black finish.
Suitable for
 Single large-screen TV or monitor installations on System X rails

How to use
Attach the interface arm to a compatible B-TECH System X horizontal mounting rail following the rail manufacturer’s spacing and load guidelines. Secure the display to the VESA 400 plate, verify the combined weight does not exceed 50 kg, and use the pop-out function to access rear connectors and cabling. Use the tool-less 8-point micro-adjustment to fine-tune the display position for uniform gaps and alignment with adjacent screens if assembling a video wall. Set the desired wall offset between 12.6 cm and 30 cm to allow sufficient cable clearance and service access.
Usage recommendations
Ensure the System X rail structure is rated for the combined weight of all mounted displays and accessories. When building multi-screen video walls, plan rail spacing and arm positions in advance to achieve consistent alignment; perform micro-adjustments after all screens are mounted. Regularly check mounting hardware and connections in high-traffic or public installations.
