Quest Manufacturing Single Screen Keyboard Tray/Arm

I use this on my Samson SRK16 rack system. The Logitech K800 fits nicely on it with the mouse tray to the right of it. I gave it four stars simply because it takes more than 1RU and anything mounted underneath it is not visible directly. You have to look under the shelf to see what's there, so if you mount any equipment that needs frequent adjustments to it, it would be difficult and annoying. Other than it, it's great for my needs. I mounted a 3U shelf below it to hold manuals, remote controls, etc.
