CTA Digital's Single Monitor Gas Spring Monitor Arm with USB Ports lives at the crossroads of style and function. This sturdy, versatile mount features a gorgeous red metal finish for just the right pop of color. A spring-loaded center joint locks to the perfect angle when tightened with the included Allen key, and swivels a full 360-degrees. The head of this sturdy unit attaches via standard VESA 75 x 75 or 100 x 100 mm plate to curved or flat monitors up to 35 inches and 24 lbs. Choose from 2 included VESA plates. The first is a non-security quick release that allows users to remove the monitor or device with the twist of a knob for easy assembly or mobility. The second VESA plate is a security option. To make the device secure, simply use the provided security Allen key to lock the VESA in place. This mount offers endless mobility, its head tilts a full 180-degrees up and down as well as left to right, and locks in place with an Allen key. The head also rotates for use in either portrait or landscape orientation. The base swivels to create the ideal viewing angle. The mount attaches in two ways. It grips counters that have a thickness range of 0.39 to 3.35 inches via padded rotary C-clamp. It can also be permanently screwed into surfaces through pre-drilled grommets with a hole diameter of 0.39 to 2.3 inches. The base comes with 2 USB ports, ideal for both charging and use with additional devices. Store Allen keys in holes at the rear of the C-clamp mount. All cables can be managed via useful clips down the spring arms.
