Option White

  • Add a second monitor to your LX arm with this extension collar kit
  • Supports displays up to 32 inches and 25 lb per screen

Dual Monitor Conversion Kit

This kit converts a single Ergotron LX Desk Mount into a dual stacking arm for two flat-panel displays. It attaches directly to the existing pole of the desk mount base. The product is designed for office professionals who need to add a second screen above the first without replacing their current mount. It supports notebooks and monitors up to the specified limits.

25 lb Capacity and VESA Compliance

The extension collar kit supports a maximum load capacity of 25 lb across the dual configuration. It accommodates VESA mounting patterns of 75 x 75 mm and 100 x 100 mm for compatible screens up to 32 inches. The setup runs out of headroom if the combined weight exceeds the limit or if the displays require a larger mounting pattern. Height adjustment and 360-degree rotation are retained for both arms.

Build Integration and Cable Management

Installation requires an existing LX Desk Mount LCD Arm with a tall pole, which is not included in this package. The kit frees up desk surface space by stacking displays vertically on a single mounting point. Integrated cable management helps route wires neatly along the extended arm structure. The silver finish matches the standard LX arm aesthetic for a cohesive look.

Questions about this item

Can the 97-940-026 kit attach to the pole of my existing LX Desk Mount base to support a second display?

Yes, the kit converts an LX Arm into a dual stacking configuration by attaching to the desk mount pole and adding a second arm for two monitors up to 32 inches.

How can I verify the arm moves correctly once installed?

After mounting, check that each display pans 360 degrees, tilts, pivots between landscape and portrait, and that cables route through the built-in management channels.

What parts are included and do I need to buy anything else?

The box contains the extension pole, collar, cap and attachment hardware; you must already own an LX Desk Mount LCD Arm with the tall pole, which is sold separately.
