Ergotron LX Arm, Extension and Collar Kit Matte Black
PRODUCT DESCRIPTION
Ergotron LX Arm, Extension and Collar Kit Matte Black (98-130-224) - 10 Years Local Warranty
Add a Third or Fourth Screen to an LX Tall Pole Arm
The Ergotron LX Arm, Extension and Collar Kit is the add-on that turns an LX Tall Pole desk-mount base into a triple- or quad-monitor workstation. In colour-matched matte black, it clips straight onto the pole so you can grow an existing LX setup instead of replacing it.
Genuine LX Arm and Constant Force Motion
The kit includes a full LX arm plus the extension, pole collar and cap, giving the added screen the same Constant Force™ lift-and-pivot feel as the rest of the system. Reposition the new display with a light touch and it stays exactly where you leave it.
Rated for Real Working Monitors
The added arm supports displays from 7 to 25 lbs (3.2–11.3 kg) with 13 inches of vertical travel. With heavier screens above 20 lbs the vertical range may reduce by up to 4.5 inches to keep motion controlled.
Seamless, Cohesive Upgrade
Because it uses matched LX components and finish, the kit blends invisibly into an existing tall-pole array — the practical way to expand capacity without a mismatched second brand on the desk. Note it is for LX Tall Pole arms and is not compatible with LX Sit-Stand systems.

Compatibility & Fit
This is an expansion kit, not a standalone arm. It attaches to the pole of an existing LX Tall Pole desk-mount base to add a third or fourth monitor. It is not compatible with LX Sit-Stand Arm systems.
The added arm carries a display of 7–25 lbs (3.2–11.3 kg) on a VESA MIS-D 75 x 75 or 100 x 100 mm plate, with 13 inches of lift. Choose matte black (98-130-224) or white (98-130-216) to match your existing LX finish. If you do not yet have a tall-pole LX base, you will need one in addition to this kit.
