The arm allows for one monitor with a size of 24" diagonally that's 20lb or less. The monitor arm has a 22.5" extention range, 160-degree monitor pan, 80-degree tilt and 90-degree monitor rotation -- allowing you to set the monitor where it's most comfortable and ergonomically sound for you.
The surface clamp of the monitor arm allows for 12.75" of height adjustment along the mounting post, plus the lift assist feature provides an additional 13" of height adjustment at the monitor. Cables are hidden along the underside of the arm to help keep your workspace neat and tidy.
Two attachment bracket options are available: an Envelop Desk-specific clamp option, or a standard surface clamp that allows you to clamp the monitor arm on any surface up to 1-7/8" thick.
