Dual stacking monitor arm

The Ergotron LX Pro Arm Dual Stacking Mount positions two displays one above the other on a single desk attachment. It suits professionals who need a compact vertical layout for coding, monitoring or creative timelines. The dark gray finish matches modern workstation aesthetics.

Replaces side-by-side dual mounts

This stacking design replaces traditional horizontal arms when desk width is limited but vertical space is available. The upgrade is worth it when workflows benefit from a top-to-bottom scan rather than a left-to-right sweep.

Holds two screens in a vertical column

The arm comfortably handles a pair of monitors aligned in a stacked configuration. It runs out of utility when the task demands a wide panoramic view or when the mounting surface cannot support the combined weight.

Questions about this item

What desk thickness does the LX Pro Arm Dual Stacking Mount clamp support?

The clamp attaches to desks up to the thickness specified in the Ergotron installation guide for model 45690293.

Which step do installers most often skip when mounting the dual stacking arm?

Many forget to torque the pivot tension bolts after setting the monitor height, so the arm drifts over time.

How often should the gas-spring tension be checked on this dual stacking mount?

Inspect the spring tension every six months and adjust if the monitors no longer stay in position.
