Enjoy a virtually tool-free assembly and easy installation with the Dell MSA20 Single Monitor Arm . Quick release mounting lets you snap a Dell UltraSharp or P-Series monitor onto the arm without tools. In addition, you can enjoy complete system mounting options with select Dell OptiPlex Micro, Ultra, and Wyse systems along with the monitor to create a tidy desk. A counterbalance indicator on the side of the arm delivers precision deployment, allowing identical tension settings to be set across numerous similar monitors. Able to handle monitors between 19 inches and 38 inches, this single monitor arm maximizes compatibility while having a small footprint. The clamp supports a 2" grommet hole or you can use the C-clamp on a convenient edge up to 2.1" thick.
