This dual monitor arm uses gas springs to support two screens independently, requiring manual tension adjustment to match specific monitor weights. It accommodates VESA 75x75 and 100x100 patterns and attaches to desks up to four inches thick via a C-clamp or grommet option. Users must loosen stiff shipping joints and calibrate the tension screws to prevent screen drifting.
