Brand new and unopened Vivo keyboard tray. We bought the wrong one. Our mistake is your good fortune. This bamboo keyboard tray with white metal frame is adjustable and easily clamps on to any desk with a top of from 1/2" to 1 1/4" thick. In other words it fits most desks. The tray for the keyboard is 27" wide and fits almost any keyboard and mouse. That is over a 50% discount on this guy!
