Manufacturer description
The Ergotron LX Vertical Stacking Dual Monitor Arm turns a crowded desk into a two-screen workstation without asking you to choose between height and reach. Its 13-inch pole and paired arms carry two displays up to 24 inches diagonal at 7 to 20 pounds each, stacked one over the other or swung side by side, and the VESA plates match both 75x75mm and 100x100mm patterns. Range of motion is where this Ergotron arm earns its keep: 13 inches of lift rising 22.6 inches above the desktop, 25.6 inches of extension, 360 degrees of rotation, and 75 degrees of tilt, so you can drop a screen to eye level…

Frequently Asked Questions
What size monitors does the Ergotron LX vertical stacking arm support?
Two screens up to 24 inches diagonal, each weighing between 7 and 20 pounds. Larger 27-inch or ultrawide panels are outside the stated range.
Will it fit my monitors' VESA mounting holes?
It supports both 75x75mm and 100x100mm VESA patterns, which covers most 20-24 inch displays. Check your monitor's spec sheet for its pattern.
Can I mount the monitors side by side instead of stacked?
Yes. Both arms ride the same 13-inch pole on two pole collars, so you can stack one over the other or position them side by side.
How does it attach to my desk?
Two ways, both included: a two-piece clamp for desk edges 0.63 to 2.6 inches thick, or a grommet mount through a hole up to 2 inches wide and 3 inches deep.
Does it come with a warranty?
Ergotron lists a 10-year warranty with technical support. Confirm current terms on the product listing before you buy.
