The Essential Quad Monitor Articulating Desk Mount is designed to mount four 10" ~ 30" displays weighing up to 22 lbs. each above your desk. The elevated display position not only adds space to your desk, but also improves your posture by allowing you to look straight ahead instead of downward. It also creates a neat and clean professional appearance, which improves the look of any home or office environment. The mount can be swiveled 180°, tilted 90° upward or downward, and rotated 360° for quick and easy swapping between landscape and portrait orientations. The quick release lever on the back of the mount allows you to raise or lower the display at will, without the need for any tools.
