Grommet Mount Base for LX Pro Arms

The Ergotron LX Pro Multi-Arm Grommet Mount Base provides a secure desk-through anchor for compatible monitor arms. It replaces a standard grommet hole to create a stable foundation for multi-screen configurations. This accessory is designed for workspaces that require a permanent, clutter-free mounting point. It supports the LX Pro arm system without occupying desk surface area.

Steel Construction With Black Finish

The base is built from durable steel with a black powder-coat finish that resists wear in daily use. Its grommet-style clamp secures to the worksurface from above and below, distributing load evenly across the mounting surface. Installation requires a pre-drilled hole and sufficient clearance beneath the desk for the tightening hardware. The fixed position suits permanent workstations rather than frequently reconfigured hot-desking setups.
