PRODUCT DESCRIPTION
Ergotron LX Dual Desk Mount Stacking Arm for Displays up to 40" Matte Black (45-509-224) - 10 Years Local Warranty
Vertical Dual-Display Efficiency
The Ergotron LX Dual Desk Mount Stacking Arm transforms your workspace into an efficient, ergonomic setup. Supporting displays up to 40 inches, this sleek matte black mount addresses cluttered desks and poor posture by stacking two monitors vertically. It is an ideal solution for professionals, gamers and multitaskers who want a modern, space-saving multi-display configuration.
Space-Saving Stacked Layout
By positioning one monitor above the other, the stacking design conserves horizontal desk space while keeping both screens within easy view. This vertical arrangement is perfect for narrow desks or setups where a side-by-side layout would not fit, helping you maximise screen real estate in a compact footprint.
Stable Support for Large Displays
Engineered to hold displays up to 40 inches and around 14 lbs per monitor, the stacking arm keeps both screens steady and securely positioned. Its sturdy construction maintains alignment during active use for dependable, long-term performance.
Smooth, Effortless Motion
Ergotron's smooth motion lets you reposition each monitor with a light touch and have it stay in place. This fluid adjustability makes it easy to fine-tune the height, tilt and angle of both stacked displays for comfortable, eye-level viewing.
Clean Matte Black Finish
The refined matte black finish complements modern workspaces while integrated cable management keeps wires tidy. The combination delivers a sleek, professional stacked-display setup that looks as organised as it performs.
