CPU4A suspends a computer underneath the desk. Not only does it keep the CPU off the floor and out of the way, but the ball bearing slides allow the unit to move back and forth up to 12" for easy access. The CPU4A also swivels side to side, making plugs on both the front and back side of the CPU equally accessible. Adjustable assembly from 5-1/2" to 9-1/2" wide and from 14" to 24" high.
