Ergonomic Monitor Arm for Desk Mounting

The Ergotron LX desk monitor arm in red clamps or bolts to a work surface and holds a single LCD screen or TV. Patented CF motion technology lets the display glide smoothly through a 13.00" height range that suits more than nine out of ten adults. The arm extends up to 25.00" so the screen can be pulled forward for work and pushed back when desk space is needed.

Aluminium Construction with Integrated Cable Routing

Built from die-cast aluminium and steel, the arm passes a 10,000-cycle motion test for long-term durability. Cables run through a channel underneath the arm, keeping power and video leads tidy and out of sight. When not in use the arm folds back over its base into a compact retracted profile that clears low shelves or cabinets.

Check VESA Pattern and Desk Thickness Before Buying

Verify that the monitor or TV carries a compatible VESA mounting pattern and falls within the arm’s weight capacity. Measure the desk or grommet hole thickness to confirm the supplied clamp or bolt-through hardware will secure correctly. Ensure there is enough clearance behind the mounting point for the arm to fold fully flat.
