Elevate Your Workspace
The Ergotron LX Dual Desk Mount Stacking Arm in polished aluminium is the perfect solution for a modern, organised workspace. Designed to support displays up to 40 inches, it stacks two monitors vertically to enhance comfort and productivity with superior adjustability. Its sleek polished aluminium finish adds durability and a touch of elegance ideal for home and corporate environments.
Space-Saving Vertical Layout
The stacking design positions one display above the other, conserving horizontal desk space while keeping both screens in easy view. This vertical arrangement suits narrow desks and compact setups, helping you maximise screen real estate without spreading monitors across the surface.
Built to Support Large Displays
Capable of accommodating displays up to 40 inches and a combined capacity of up to roughly 18.1 kg, the stacking arm offers robust support for dual monitors. Its high-quality polished aluminium construction ensures stability even when fully extended, delivering long-lasting performance in busy environments.
Smooth, Effortless Motion
Ergotron's smooth motion lets you reposition each monitor with a light touch and have it stay where you set it. This fluid adjustability makes it easy to fine-tune height, tilt and angle for both stacked displays, supporting a comfortable, eye-level view.
Premium Finish and Tidy Setup
The polished aluminium frame delivers a striking, professional look while integrated cable management keeps wires neatly routed. The result is a clean, elegant stacked-display workstation built to withstand years of use.
