I’ve had this keyboard tray in my garage for several years. I salvaged it off of some old desks that were being discarded. Currently, I’m in the middle of organizing my workshop and the junk in the garage. I decided that I’m either going install this keyboard tray today or it’s going in the trash. I had to flip the keyboard tray upside down and use bolts to hold it in place so that the wireless keyboard would clear the steel support bar that’s underneath the lower portion of the mobile desk. Now my wife Sylvia has more desk space because the keyboard is now located in the tray below the work surface of the desk.
