CTA Digital's Single Monitor Slim Spring Arm with Dual USB Ports lives at the crossroads of style and function. This sturdy, versatile mount features a gorgeous white finish that's sure to elevate the look of any office décor – all with smooth movements for a great work experience. A spring-loaded center joint locks to the perfect angle when tightened with the included Allen key, and swivels a full 360-degrees. This mount also has a 180° rotation stop feature that prevents the monitor arm from swinging into screens or walls. 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 32 inches and 19.8 lbs. It slides out of a locking bracket, for simple mounting. The 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 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.
