This deskmount dual-monitor arm lets you mount two 13" to 27" VESA mount monitors, each weighing up to 17.6 lb. (8 kg), onto a single low-profile base. It gives you flexible desk-clamp or grommet-hole mounting, letting you save space while creating an ergonomic workspace in any office environment.
With a stable dual-arm design, the double-monitor mount lets you create more usable work space by mounting your monitors side by side on a single base. The screen mount features a flat low-profile back that lets you position your displays against a wall or cubicle wall.
The computer monitor desk mount features adjustable height along the pole. The smooth +/- 30° tilt motion and +/- 30° swivel make it easy to find the optimal viewing angle. You can also rotate your display 360° for portrait or landscape viewing, and make sure your displays are perfectly aligned using the micro-adjustment knob.
The dual-monitor arm is easy to install, with the desk-clamp or grommet mount (hardware included). Integrated cable management keeps your workspace organized. It works well with most desks, including sit-stand workstations.
Adding two monitors gives you the extra screen space you need to simplify multitasking and maximize your productivity.
