Used this build a custom sliding tray for my keyboard/mouse.Pros:- Great quality- easy to setup and make adjustments- Smooth sliding- Grips table wellCons:- Price could be a little lower, but quality makes up for it

Love it, was able to make my keyboard shelf the exact size I wanted. Great product, easy to install.

Wobbles and loosens a bit over time, but overall pretty sturdy and functional. May have to retighten screws every few months to reduce the wobble, but it is supporting a ~10 pound melamine board

Completely adjustable in height and depth. Great for light to medium under desk items laptops, keyboard and mouse, midi keyboards ect.

I am a content creator, music producer. I've been lusting for my 61 keyboard controller to fit perfectly under my desk. With the ability to access the keyboard when needed.With a couple of tweaks to my main desk frame and new shelving I was able to not only "pull off" a descent set up. but a "perfect" set up.Glad I opted for the extended tray option. This unit is easy to assemble and of good quality. Great buy. Thanks.

I am using a table as a desk, it works well but I wanted more room on it so a keyboard tray was the answer. I bought this set for using your own board and it worked very well. I used a 3 foot x 11 inch pine board I sanded smooth and have had no issues. The clamps came with everything needed expect the board. Its sturdy slides easily and has tension locking so it does not slide in and out when do not want.

Heavy duty, right on money, only thing the screws have been a little longer just by .100 (Decimal 100) could have been better. Nice experience building the under desk tray I needed for my Midi controller for my little home studio setup - was totally not expensive & It is a 5 star product.

I bought a used solid oak wood desk without a wide keyboard shelf. Apparently the former owner retired but used a manual typewriter and paper for work!Anyways. I wanted a 36 x 18 x 1 inch [ finished lumber is not actual size ] shelf and these brackets without shelf are perfect. I assembled all the parts, adjusted the shelf to a comfortable height and then unrolled an extra large desk pad to keep the mouse happy.The clamps secure the whole thing to the desk and are as great as the maker intended.
