Dual Desk Mount Kit

The Ergotron LX Pro Arm is a desk mount kit designed to hold two monitors on a single base. It suits professionals who want to reclaim desk space while positioning screens at comfortable viewing angles. The arm structure allows independent movement of each display for flexible workflow arrangements. Installation uses a clamp or grommet attachment for secure mounting.

Two-Monitor Setups Only

This kit suits users who need exactly two screens side by side on one desk mount. Buyers who want more displays or a single-monitor arm should look at other configurations. The fixed dual layout does not adapt to triple-screen arrays or asymmetric monitor sizes beyond the arm's adjustment range. Renters or temporary workspaces may prefer freestanding alternatives that avoid desk drilling.
