During the years I working as customer service representative on an incoming toll-free line, I had an office designed unit like that in my cubicle. It was about 16-17 inches wide and was easily accessible of my desktop. Are you able to have holes drilled in the metal binder portion to insert a screw? You could fasten from the backside with a metal nut. I forgot to mention that the viewing unit was angled --- think of the catalog in an auto supply store, :-)
