Compact yet sturdy, the 3M Dual-Swivel Monitor Arm is the handy accessory that lifts monitors up to thirty pounds for better positioning that works for you, not against you.

With a dual-swivel system built into the design of the arm, the 3M Monitor Arm MA140MB can be easily adjusted for height and depth.

Integrated cable management keeps your wires neatly tucked out of the way, and a heavy-duty mounting system allows for the arm to be installed onto the edge of a desk or mounted in a desk grommet.

It's the easy-to-use monitor solution to bring you into a new era of working - ergonomically.
