Dual Monitor Arm for 25-inch Displays

This Ergotron LX Dual Direct arm mounts two screens up to 25 inches side by side. It is built for desk workers who need both monitors to move together as a single unit. The polished aluminium construction suits professional and home office environments. Installation is designed to be straightforward from the start.

Motion Range and Tested Durability

Each arm provides 360 degrees of rotation, 30 degrees of tilt and 360 degrees of pan for flexible positioning. Patented Constant Force technology keeps movement smooth without manual tension tweaks. The mechanism passes a 10,000-cycle motion test to verify long-term height adjustment reliability. Normal operation stays quiet and stable across the full range.

Desk Mounting and Weight Support

The direct desk mount clamps or bolts to the surface for a secure, low-profile footprint. Polished aluminium resists daily wear and keeps the setup looking clean. Combined load capacity is 11 lb, so both screens must stay within that total. Buyers with heavier or larger monitors will need a different mounting solution.

Questions about this item

How is the LX Dual Direct Arm secured to the desk and which step is often missed?

The arm mounts directly to the desk surface using the supplied clamp or grommet hardware; the step often missed is tightening the base bolts to the specified torque so the 360-degree rotation remains stable.

What maintenance or replacement will the LX Dual Direct Arm need after extended use?

The arm is tested to 10,000 motion cycles, so under normal use no scheduled maintenance is required; only the gas-spring cylinder would need replacement if height adjustment becomes uneven after many years.

What is the first limit reached when the LX Dual Direct Arm holds a monitor continuously at full extension?

The 11 lb weight capacity per arm is the limiting factor; exceeding it causes the Constant Force™ mechanism to lose its counter-balance and the monitor will drift downward.
