Our AHM (Adjustable Height) Monitor Arms feature 120° of height adjustability and 180° side to side motion so that you can easily adjust the position of your attached monitor. The Adjustable Height Monitor Arms can also be locked in any position to maintain the desired height adjustment. The AHM can be mounted directly to any equipment rail or wall channel. Integrated cable management allows you to tuck away cords so that they move with the AHM.
