Key Features

  • High weight capacity: Supports monitors up to 9 kg, suitable for large ultrawide displays.
  • Extensive range of motion: 75° tilt, 360° swivel, 360° pan, and 33 cm (13 inches) of vertical lift.
  • Tool-free height adjustment: Constant Force (CF) technology lets you adjust height with one finger, even with the monitor attached.
  • VESA compatibility: Works with 75×75 mm and 100×100 mm VESA patterns, covering virtually all standard monitors.
  • Dual mounting options: Includes both clamp (desk thickness 10–65 mm) and grommet mount (hole diameter 10–55 mm) hardware.

Compatibility & Installation Guide

The arm fits desks with a thickness of 10–65 mm for clamp mounting, or grommet holes 10–55 mm in diameter. The included VESA plate supports both 75 mm and 100 mm patterns without adapters. A Phillips screwdriver is needed for the clamp, but the arm assembly itself is tool-free. Built-in cable clips keep wires organized.

Ideal For

  • Users who want to free up desk space and improve ergonomics.
  • Professionals who frequently adjust monitor position (programmers, designers, traders).
  • Owners of large monitors (27–34 inches) needing a stable, premium arm.
  • Those building a white-themed workspace.

Cautions

  • Do not exceed the 9 kg weight limit. Check your monitor's weight before purchase.
  • Avoid glass or thin particleboard desktops; the clamp pressure may cause damage. Solid wood or metal desks are recommended.
  • The arm extends up to 53 cm (21 inches). Ensure your desk depth is sufficient.
  • This is a single-monitor arm. For dual setups, consider the Ergotron LX Dual Monitor Arm (45-509-216).
