FSA1 features an arm adjustable to the weight of the monitor, from light (7 pounds) to heavy (up to 22 pounds) monitors. The arm itself offers 14" of vertical adjustment. The screen can tilt up or down 20 degrees, and the screen mount and arms can rotate up to 359 degrees. Fully extended, the monitor can project a maximum of 22" from the mounting post. The system includes wire management to help conceal the wiring. Arms attach to plates on back of most flat screen monitors, which must have the VESA 75 mm or 100 mm mounting pattern. Installing is easy; just drill a single 15/32" (12mm) hole in desk or work surface, fasten from underneath.
