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

I needed a custom sized tray to make space for both a mouse, full keyboard, and little temporary space to jot notes, place smartphone, or any other temporary items that I need to take care of. Since I already had a stand-up keyboard stand made of solid wood that I wanted to re-use the top, I decided to purchase just the rails and get rid of the stand legs.This set of rails is smooth and sturdy, clicks when both pushed fully in and fully out. Since these are just rails, you can place them anywhere in almost any distance apart to fit custom sized trays. I put my 3/4" thick solid wood top that I re-purposed from the stand (it's slightly under 3 ft wide and 9" deep) and the rail can slide it without wobbling or shaking.The metal the rails and clamps are made of are solid and sturdy. The screws fit well and hold well. There are 3 holes and 3 screws for each rail but you only need 2 (choose the two that balance out the tray so it doesn't put too much pressure), I only used 2 wood screws per rail since my wood tray was only 9" deep and was placed slightly outward, and that still held well. Overall the assembly was easy, you just need a drill and a screwdriver for well-finished install.Perfect for custom sized keyboard trays.

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.

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

This is easy to assemble by using a standard length of board. It is very flexible in order to create the best keyboard holder for your situation.

Whenever I post my desk setup online, the number one question I get is this: what are you using to hold up your midi keyboard? It’s these clamp on rails, and I’ve referred multiple dozens of people at this point (you’re welcome, Vivo, LOL). They are an absolute game changer for creating more desk space if you use a relatively thin midi keyboard. I had to flip the mounting brackets upside down to create enough space for my keyboard, but it still works perfectly. Depending on how light the keyboard is and how the keyboard is designed on the underside, you might not even need to add a wooden tray beneath it (I don’t have to — the brackets sturdily cradle the keyboard). It is such a perfect, easily customizable solution that I highly recommend to fellow midi keyboard players.
