From Ergomotion , the adjustable CPU holder also fastens under the desks and allows the user to place the CPU in the holder off the floor.
The adjustable CPU holder is easily adjusted both in width (110mm-250mm) and in height (300mm-500mm) to accommodate most PCs on the market. The CPU holder allows easy access to the plugs and ports. The CPU is kept off the floor allowing more room under desk and reducing the risk of breakage.
When used in conjunction with the cable tray it allows for a clean uncluttered space under the desk.
