Ergotron LX Series LX Dual Stacking Arm Tall Pole 101.6 cm Aluminium Clamp 20 kg

22" (55.9 cm) tall pole provides configuration flexibility and is ideal for larger displays. The LX Arm system supports multi-monitor setups and can be expanded with the LX Arm Extension and Collar Kit to add a third or fourth display. Designed to improve ergonomic positioning, the arm allows extensive range of motion and helps reduce eye, back and neck strain while folding arms save space in constrained environments.

Advantages

The monitor arm offers stable, reliable support with constant force lift-and-pivot motion technology, enabling smooth height adjustment. It passed a 10,000-cycle motion test to ensure long-term performance. A two-piece mounting clamp with keyhole-shaped holes simplifies assembly and two clamping screws secure installation. Monitors can be rotated between landscape and portrait orientations for full-page viewing without scrolling.
