Extend Your LX Arm for Dual Monitors

This kit converts a single Ergotron LX arm into a dual stacking configuration. It attaches to the pole of a compatible desk mount base and supports two displays up to 32 inches each. The maximum load capacity is 25 lb per screen.

VESA Mounting and Adjustment Range

The extension works with VESA 75 x 75 and 100 x 100 mounting patterns. It provides 360 degree rotation, plus pan, tilt and pivot adjustments. Integrated cable management keeps wiring tidy. Height adjustment is supported for ergonomic positioning.

Build Requirements and Space Gains

You need an existing LX Desk Mount with a tall pole to install this kit. It adds a second monitor without requiring an additional desk base, freeing up surface space. The silver finish matches standard LX components. Not suited for single-monitor setups or non-LX mounting systems.

Questions about this item

How do I attach the extension pole to my existing LX desk mount pole, and which step is often missed?

Slide the collar over the pole, insert the extension, then tighten the collar clamp securely; the step often missed is fully tightening the collar clamp so the joint cannot rotate under load.

What part will need replacement after years of daily height changes?

The gas spring inside the original LX arm eventually loses force; the extension pole and collar are solid metal and do not wear out.

At what combined monitor weight does the arm stop staying in position?

The kit is rated for 25 lb total; exceeding that limit causes the arm to drift downward.
