VIVO Clamp and 12 inch Rail Set for DIY Custom Wooden Keyboard Trays (Tray Not Included), Under Desk Pull Out Slider Track with Extra Sturdy C-clamp Mount System, Black, MOUNT-RAIL02

If u want to add ur own sized tray and the color that match ur table too this is these are the ones u need and these are very good quality too

Do what they meant to do I actually made a large shelf fairly wide and handles it without any problem. Have got a Music midi keyboard on it and works very well.

très solide

Feels sturdy and easy to assemble, particularly as it clamps onto the desk rather than having to fix it underneath. It looks good too.

Very good product does the job and the runners can be fit onto any wooden piece you want and can be adjusted very heavy quality too and opens and slides well too. Overall good purchase

Because of my tiny desk I have, that is only 23.3 inches wide. I could not find a keyboard tray that was small enough to fit desk. Smallest I could find was 20 inches not including the clamps width, as my desk table top is also to thin to screw in another type. Then I came across this item selling just the clamps and rails. It was perfect, I was able to customize my tray at 17 1/2 inches; sits perfect under my desk. The tray is easy and smooth to pull it out or push back in, and its very sturdy.
