Dual monitor sit-stand accessory

The Ergotron 33349200 converts a fixed desk into a height-adjustable workstation for two screens up to 24 inches each. It clamps to the rear of the surface and lifts both monitors and keyboard together using patented Constant Force technology. Office workers and hot-desk users gain instant sit-stand transitions without tools.

Practical limits of the clamp mount

The desk clamp requires a clear rear edge thick enough to accept the mounting hardware; grommet mounting is not described in the data. Total supported weight is 25 lbs across both displays, and each screen must not exceed 24 inches diagonal. The column provides 22.8 inches of vertical travel and 360-degree rotation at the VESA MIS-D interface.

The 25 lb dual-display capacity decides fit

Two monitors plus the worksurface and keyboard tray must stay at or below 25 lbs combined, so heavier 24-inch panels or adding a third screen will exceed the limit. Buyers with larger or heavier displays, or who need a freestanding base instead of a clamp, cannot use this model.

Questions about this item

Should I choose the 21.3-inch or 24-inch screen limit for my dual monitors?

The specifications list a maximum screen size of 21.3 inches and a separate limit of 24 inches; use the lower 21.3-inch figure as the governing limit for this model.

What does the 22.8-inch lift figure mean when the workstation is on my desk?

The 22.8-inch lift is the vertical travel range, letting you raise both monitors and keyboard together from seated to standing height in one motion.

How does the MIS-D VESA interface cap the monitors I can mount?

MIS-D is the VESA mounting standard used on the crossbar; it defines the hole pattern for attaching screens up to the stated 21.3-inch and 25 lb limits.
