These things worked great for my electronic piano. Actually, it’s a midi controller, but same thing if you don’t know what that is. I got a piece of wood at Lowe’s. 3/4” Thick X 36” Wide X 12” Deep. It works great. My keyboard weighs 19 pounds. It feels pretty solid. I’m happy.

The media could not be loaded. Using the 12" rails with a 10" x 36" white shelf from Home Depot (which cost about $11). The hardware feels sturdy. It's just slightly wobbly while pulling in and out, but otherwise stable especially when actually using it which is the most important. Love that I can adjust the height higher/lower in the future if needed. Installation was straightforward with no surprises, and all needed screws were provided. Happy with my purchase and expecting to get years of use out of this.

I only ordered one, but for some unknown reason, I received two of these in the same box: two left sliders and hardware bundled in bubble wrap, and two right sliders and hardware in a separate bubble wrapped bundle. They did appear to be new and fully intact, but unlike other reviewers' photos, neither came in a branded box and neither included instructions. Not one word, not a website, not a QR code, nothing. Fortunately, the product page has some tiny illustrations that I was able to squint at. However, I had to adapt the instructions.The first two steps, assembling the parts, were easy. You attach the tray (a board that is not included) to the slider, then attach four L-shaped brackets (as discussed later, I had to detach the back two). Extra screws were provided, which came in handy when one fell then apparently crossed to another dimension. But attaching everything to the underside of the desk was NOT easy, and in fact took several days to figure out. It also necessitated buying a long 12" screwdriver. If you can turn your desk over, it will simplify the process, but I had too much setup going on to do that. A second person with steady hands and limitless patience would also work.Installation requires drilling pilot holes to the underside (not actually part of the instructions but seems pretty necessary), then screwing the four L-shaped brackets to the desk *while they are attached to the tray.* That is quite unwieldy. I worked alone, so following the directions would be impossible because I'd have to hold the tray up at the same time I'm trying to screw the brackets in, while sitting or lying in a tight space under my desk, wearing a headlamp and safety goggles to block drilling dust. I got a few cricks and cramps as I contorted myself in awkward positions.Luckily, there were some screw holes from the previous tray that I was replacing, but not all of them aligned with the new brackets. I only had to drill a few more and at least I could be confident that they were perpendicular to the desk edge. This would have been much harder without existing holes because there was a structural bar running between the places where the screws should go, so even a template would not have been easy to work with.The L brackets that attach to the underside of the desk have a triangular side that blocks a side view of the screw holes, making it difficult to work any way but directly underneath or facing the bracket. In other words, I could not sit at the front of the desk and reach the back brackets because the triangles blocked me. I had to go from the floor or through the side of the desk, which would be impossible for many desks but luckily mine is open on the sides.With the pilot holes drilled, I detached the back brackets from the assembly to screw them in separately, then, using a small cabinet and some shims, I propped up the rest of the assembly and aligned it so I could attach it to the back brackets. Lastly, I screwed the front brackets of the assembly to the desk. Sounds easy but the whole thing was a cascade of obstacles.The provided wood screws provided did not work well with my desk so I used the screws saved from the previous tray.Now that it's in, it works and my setup is much more ergonomic, though it slides a bit tightly. One last note: As far as I could tell, the sliders do not pull out entirely, in other words they don't allow the tray to separate completely as you can with most drawers. Having that ability would simplify installation greatly, as you could install the brackets and rails, then as long as they were properly positioned, you could simply push in the tray.

Just what I needed to add slide-out keyboard draw to my computer desk. Hardest part was holding it up to drive screws to attach to underside of desk. Much easier to do if you attach draw slides before standing desk upright.

This is a great replacement for a broken keyboard tray. I am pleased with the smooth glide of thisproduct. My keyboard tray has new life. Thank you.

I give this three stars, but I can't honestly say it is the product's fault. I think this could be a good solution for flat tables, not if you have a desk with a small area where your legs fit. The reason, if you watch the video, is that to be able to attach the screws to the desk (the last step), you HAVE to have room to get a screwdriver / drill with screw bit to the outside of the brackets. I found I could barely make the setup fit within the 24" space I was working with, but there was zero possible way to get the wood screws up into the bracket.

Seem to be as good as anything. I would buy again.

Sturdy for my under desk keyboard tray. I wish the travel was a little further. 1 locks the other side doesn't... could be me not setting it up right. Holding up a 3' wide by 30" deep 3/4" piece of birch wood shelf. Screwed it into the bottom of my 1 1/2" thick butcher block desk. It works fine not that high end but works for me.
