Our take on the Kensington SmartFit Desk Mount For Monitor K55409ww

The Kensington SmartFit K55409WW is a dual monitor desk mount for two screens up to 32 inches and 8 kg each. It uses a gas-spring arm with tilt, swivel and rotation, plus SmartFit color-coded height settings that help you set the arm to your body height without guesswork. Cable management runs along the arm, and the clamp or grommet base frees desk space. It sits in the same class as Ergotron LX and Amazon Basics dual arms: solid steel and aluminum build, tool-free VESA plates, but a shorter reach than premium arms and no laptop tray in the box.

What reviewers say

Owners rate the K55409WW well for build quality and the SmartFit height guide, which makes first setup quicker than most dual arms. Complaints center on arm reach and on heavier screens sagging slightly at the joint.

Questions and answers

Does it fit two 32-inch monitors?
Yes, each arm holds a screen up to 32 inches and 8 kg. Check your monitor's weight with its stand removed before buying.
What VESA patterns does it support?
It supports 75x75 and 100x100 VESA patterns, which cover most monitors. Monitors without VESA holes need an adapter.
Can it clamp to any desk?
It mounts by desk clamp or grommet. The clamp needs a flat edge without a lip or bevel, and very thick tops may exceed its range.
Does it rotate to portrait?
Yes, each screen rotates 360 degrees, so portrait mode works for coding or reading.
Is a laptop tray included?
No. The box has the arms, VESA plates, clamp and grommet hardware and cable clips. A laptop tray is sold separately.
How is it different from the Ergotron LX dual?
The Kensington adds the SmartFit height guide and costs less, but the Ergotron LX has longer reach and a longer warranty.
