Converts LX Arm to Dual Stacking

This kit adds an extension pole and collar to an existing LX Arm, enabling a dual stacking arm configuration. It attaches directly to the pole of a compatible desk mount base. The accessory supports a maximum load capacity of 25 lb per display. Supplied hardware includes the extension pole, collar, cap and attachment fittings.

For LX Arm owners adding a second screen

Suitable for users with an Ergotron LX Desk Mount LCD Arm who want to mount two flat panel displays up to 32 inches. Each screen must weigh 25 lb or less and use a 75 x 75 or 100 x 100 VESA pattern. Not suited for single monitor setups, heavier displays, non-VESA screens or mounts from other manufacturers.

25 lb per display weight limit

The decisive specification is the 25 lb maximum load capacity for each mounted display. Both monitors in the stacked configuration must fall at or below this figure. Verify the weight of each panel before purchase; exceeding the limit risks instability and voids the ten year limited warranty.
