Marathon Computer has announced the DisplayLock, a sleek safety add-on that keeps Apple Cinema Displays from being accidentally knocked off desks. “DisplayLock’s solid aluminum bar fits through the bottom of the Cinema or Studio Display’s plastic kickstand, and is secured into a bracket attached to the desktop. The bracket can be secured in a fixed position, or by means of a single center screw that allows the Display to swivel. Either way, the easel is prevented from being accidentally scooted off the edge of the desk.” The Marathon DisplayLock is priced at US$19.
