The height adjustment range of the M2.1 is 10 inches, and it weighs just 5.7 pounds, making it easy to install and adjust. The arm also comes with a 15-year warranty, ensuring that you can rely on it for years to come.

Overall, the Humanscale M2.1 Radial Monitor Arm is a high-quality and durable solution for mounting your computer monitor. Its innovative mechanical spring design and sleek profile make it a top choice for anyone looking to optimize their workspace and reduce eye strain.
