Heavy-duty monitor arm for 34–49 in screens

This single monitor arm holds one display from 34 to 49 inches weighing between 22 and 44 lbs. It mounts to a desk using either a C-clamp or grommet base and supports VESA 75, 100 and 200 mm patterns. The gas-spring mechanism provides smooth height, tilt and swivel adjustments for ergonomic positioning.

Gas-spring mechanism with 10000-cycle durability

The arm offers a height range of 8.1 to 19.1 inches above the desk and extends up to 21.7 inches from the mount point. Movement includes 80° upward tilt, 15° downward tilt, 180° or 360° swivel and 360° screen rotation. All motions are rated for 10000 cycles of operation.

Hardware kit covers two mounting styles

Included fasteners support both C-clamp and grommet installation so the arm can be fixed to a desk edge or through a grommet hole. VESA mounting hardware for 75, 100 and 200 mm patterns is also supplied. No software or additional accessories are bundled.

Questions about this item

How do I attach the C-clamp or grommet mount to my desk, and what step is often missed?

Secure the base with the C-clamp on desks up to 3.3" thick or through a grommet hole; the step often missed is tightening both mounting bolts evenly so the arm stays level under a 44 lb monitor.

What maintenance will the gas spring mechanism need after extended use?

The gas spring is sealed and rated for 10000 adjustment cycles; no lubrication or internal service is required, only occasional bolt checks to keep the 360° swivel and 180° tilt smooth.

At what point does the arm reach its limit when I keep extending a heavy ultrawide monitor?

Full extension stops at 21.7" from the mounting surface; beyond that the gas spring cannot counterbalance a 44 lb load, so the monitor will begin to droop.
