Fixed Mount B-Tech SYSTEM X BT8390 VESA 400 Pop-Out Arms 50kg

The B-Tech SYSTEM X BT8390 VESA 400 Pop-Out Arms are fixed mount interface arms designed for assembling videowalls and multi-screen installations. Compatible with medium to large screens (up to 50 kg), this mount attaches to System X horizontal rails and provides pop-out access for easier installation, cabling and maintenance. The universal modular design supports landscape and portrait orientations and offers micro-adjustment and a height adjustment range of -20 to +20 mm for precise alignment.

Advantages

Tool-less micro-adjustment enables accurate alignment of adjacent displays. A mounted depth of 105.4 mm from the wall provides space for cable and connector access, while pop-out functionality simplifies screen installation and maintenance. The mount supports screens up to 50 kg and fits VESA 400 patterns.
