Dual Monitor Arm for Desks up to 27 Inch Screens

The Ergotron LX Dual Side-by-Side Arm mounts two LCD displays up to 27 inches on a single desk clamp. It includes two articulating arms, two extension brackets, a T-bracket and a pole made from aluminium and durable steel. The white finish suits modern workspaces and the assembly supports side-by-side positioning for expanded screen real estate.

Suited for Dual Screen Workstations Not for Single

This mount suits professionals who need two screens at matched height and reach for productivity tasks such as coding, design or financial analysis. Buyers who only need to support a single display should consider a single-arm solution. Those with screens larger than 27 inches or heavier than the arm's capacity will need a different mounting system.

Questions about this item

How can I check the LX Dual Side-by-Side Mount is holding both screens securely after installation?

After clamping the pole to the desk, attach each monitor to its articulating arm and verify the VESA brackets sit flush. Gently pull each display forward and sideways; the arms should move smoothly and lock in place without sagging, confirming the 27-inch weight limit is respected.

What hardware comes in the 45-491-216 box and what must I source separately?

The kit includes a desk clamp mount, pole, two articulating arms, two extension brackets and a T-bracket. You will need to provide the monitors themselves and any VESA mounting screws that match your specific display models.
