The Mobile Series integrates technology and convenience to allow the user to easily move an entire computer system from one room to another. The Mobile WorkStand quickly adjusts to a sitting or standing user height, while still providing an ergonomically correct work environment. Customize your system for mounting a flat panel monitor, laptop, keyboard, mouse, CPU, UPS, cables and more. The Mobile WorkStand features easy-to-clean, heavy-duty steel construction. To attach 400, 300 or 200 Series vertical mount arms and peripherals to the Mobile WorkStand, you need these two vertical pole mount brackets that accommodate 2-inch pole diameter.
