DUAL MONITOR SIT-OR-STAND
DESKTOP WORKSTATION

2
The Gabor Dual-Monitor Sit-or-Stand Desktop Workstation can securely support two flat-panel or curved monitors from 17 to 27 inches. A sturdy two-section
articulating arm offers control over swivel, tilt, rotation, and height for precise monitor and keyboard placement for sitting or standing while you work.
A keyboard tray is designed with ample room for a full-sized keyboard and mouse. And two separate accessory slots can hold two devices like a smartphone
or calculator, and a handheld recorder. This workstation mounts to a desktop with a heavy-duty grommet or low-profile clamp that will fit into a space with
tight clearance, like a cubicle. Integrated cables connect with your computer to offer convenient desktop access to two USB 3.0 ports. Cable guides organize
your cables and minimize clutter.
