The ED-LX-55NV01 is a unique product. It is a wall mounting arm for a laptop with a height adjustability of 20" that provides the user an ability to sit or stand while working. With a horizontal reach of 33" and side-to-side adjustment of 62", it is ideal for dental offices, libraries and offices. This product is made up of two parts - the arm provides the vertical, horizontal and side-to-side flexibility and the laptop holder provides a safe resting place for the laptop. With four adjustable clasps and an open back, this holder, which attaches to the arm directly, allows for air circulation and prevents overheating of the laptop.
