The KPM-312 allows you to reclaim your valuable desktop space, while promoting a more ergonomic posture in your work station. This rugged, black finish mount is constructed of high-grade steel and is designed to support flat or curved screens of up to 27 inches in size and 14.3lb in weight. Its sturdy grommet and C-clamp base offers superb stability even when fully extended. By integrating an innovative gas spring mechanism designed to counterbalance the weight of the monitor, it becomes incredibly smooth to extend, retract, swivel and tilt, so as to achieve optimal visibility no matter your sitting position. Installation is also greatly simplified by the use of pear-shaped slots in the VESA plates. And for a smart, cleaner look, the mount features channels under each arm to route cables and keep them neatly organized at all times.
