Dual monitor arm for 32-inch screens

The Ergotron HX Dual Monitor Arm supports two displays up to 32 inches diagonal and 5 to 17.5 pounds each. It is built for professionals who need flexible positioning across a wide range of VESA 75x75mm and 100x100mm compatible monitors. The matte black finish suits modern office environments. Buyers needing support for screens larger than 32 inches or heavier than 17.5 pounds per arm should look elsewhere.

Clamp or grommet mounting included

Installation uses the supplied two-piece desk clamp for surfaces 0.6 to 2.6 inches thick or a grommet mount through a desk hole. The package contains the arm, extension, hinge bow, two monitor pivots and a handle for assembly. Ensuring the desk thickness falls within the clamp range is the most common oversight. Very thick or unusually thin desktops may prevent a secure fit without additional hardware.

11.5 inches of vertical lift range

The arm provides 11.5 inches of lift, allowing monitors to reach 20.6 inches above the desktop. Combined with 360 degrees of rotation and 75 degrees of tilt, this range determines whether the screens can be positioned at the required ergonomic height. A hinged bow enables outward folding for collaboration. Adding the HX Triple Monitor Bow Kit accessory 98-009-026 expands capacity to three screens.

Questions about this item

How do I verify the arm holds each monitor at the correct height after installation?

Raise the monitors to the maximum 20.6 inches above the desktop and confirm they stay level; the 11.5-inch lift range should operate smoothly without drifting.

Which mounting hardware is included and what must I supply?

The box contains the arm, extension, hinge bow, two monitor pivots, handle, two-piece desk clamp for surfaces 0.6 to 2.6 inches thick, and a grommet mount; no extra hardware is required for standard desks.

Should I choose the dual-arm model or add the triple bow kit for three screens?

This model supports two monitors up to 32 inches and 17.5 pounds each; add the HX Triple Monitor Bow Kit (98-009-026) only if you need a third screen on the same mount.
