3M Dual Swivel Monitor Arm 30lb

The 3M MA140MB is a dual swivel monitor arm designed to hold two screens on a single pole. It offers 360 degree rotation, 180 degree pan and a tilt range of plus 15 degrees to minus 90 degrees. Clamp mount hardware secures the arm to desks up to 4 inches thick. Pole height adjustability reaches 7 inches for ergonomic positioning.

Ideal for two-screen setups on shallow desks

This arm suits users who need independent screen movement and a compact footprint. The 30 pound total weight capacity covers most standard office monitors. Buyers who need more than two screens or a higher per-screen load should look at alternative mounting solutions.

VESA MIS-D compliant mounting pattern

The arm attaches to displays using the VESA MIS-D standard. Verify that each monitor carries this hole pattern before purchase. If your screens use a different mounting standard, this arm will not fit without an adapter.

Questions about this item

Does the arm generate any heat or noise during all-day use?

No, the arm is a passive mechanical mount with no motor or fan, so it adds no heat or audible noise to the workspace.

What mounting hardware do I need on my desk before installing this arm?

The included clamp attaches to desks up to 4 inches thick; no separate bracket or grommet kit is required.

Will a monitor that only tilts ±15 degrees still benefit from the arm's +15/-90 degree tilt range?

Yes, the arm provides the full +15/-90 degree tilt regardless of the panel's own stand limits.
