Stand Up Desk Store Large Clamp-On Retractable Adjustable Height Under Desk Keyboard Tray | for Desks Up to 1.5" (Large, 33" Wide)

Super sturdy, big enough for a full size keyboard and mouse, stays put while im typing and using the mouse, very easy to install.

This is an inexpensive addition to clip onto your existing desk provided you have the right desk dimensions. The clamps need about 1.5" depth into the desk for a secure clasp. The desk clasping section should be no more than 2" thick.Assembly is very easy and my version came with a small screwdriver to make it even easier.The best feature imo is that this may be the only keyboard base that has three height settings. Obviously, if you have a standing desk, you only need to raise the desk for proper height. But what this might solve is those among us who tend to lift our fingers high when typing. I chose the lowest setting for that purpose and it works well. I can type with the tray under the desk even, and while I cannot see my fingers, I know that they will not hit the underside of the desk.The only downside is that this is a wobbly add-on. You want to pull the tray from the center, not from the sides. The sliding mechanism is fairly small so it can easily get stuck at an angle if you do not pull the tray out from the center. Not a big issue if you're gentle with it.highly recommend.

I purchased this in April 2020, (27" which appears no longer available) for my sit stand desk, it's now August 2024 and it's still working great.Pros:- Very easy to install, no intense assembly required.- 1 piece, not split in the middle- Glides easily, unless a screw has gotten loose or falls out (easy fix)Cons:- No stopper/fence in the back so my wireless mouse periodically flies out the back and onto the wood floor. I find this VERY annoying.- Occasionally it gets wiggly, or a little lopsided, because a screw has fallen out of one of the side clamps or a screw needs to be tightened. I suspect normal wear and tear causes it to eventually jiggle loose. In the 4 years I've had it, I probably lose a screw ~ once per year, thankfully I have wood floors so it's easy to find & put back in.Searching for another keyboard tray now, for a different desk is brutal - so many split in the middle pieces of garbage.

I love this so much!!! My desk is about 8 years old and the keyboard tray broke maybe a year after I bought it. I have been without for so long because I didn't think I'd like how a replacement tray would look. This tray actually looks very professional and makes my desk look more modern. It was very easy to install and set up and I've had no issues with it since. It glides very smoothly and the rails are made of nice heavy duty material. I write a lot and this is really perfect in every way. It supports me leaning on it with my elbows (despite the directions saying not to do this) and its the perfect height for my chair. The rounded edge is sooo important here. I looked at other brands but from experience, the squared off edges are rough on my wrists and arms and the smooth edge on this one is so nice. No more scraping. I would highly recommend to anyone needing a replacement keyboard tray or anyone wanting to add a tray to a desk or table that doesn't already have one. It's great!!!

This really should have been 5 stars. The tray itself was perfect. And it was large enough that it could easily support both my keyboard and mouse. It seems very sturdy, the rollers that allow the tray to go in and our worked seamlessly and It was easy to put together! I really thought it was going to be perfect for me. But it didn’t work for my desk! My desk is slim and L shaped and running along the front of it, about 1 1/2 inches back from the edge is a 3/4 inch square metal support bar. That bar is just far enough forward that it doesn’t allow the round piece that screws up from the bottom to lay flat So the tray is unable to attach itself all the way back to allow it to be secure. So I can’t use it and need to return it. I’m not happy about it and when I called to see if that had some attachment or after market thing that could make it work, or a pull out tray with a different design I was told they don’t have many choices and nothing would work. So that it why it is only 3 stars instead of 5. They need to know that not every person works in an office with a big executive desk. This is 2013 and after Covid a lot of us work from home and due to workspace size we need to make different choices about our desk and other things. So they also need to up date the designs to keep up with the times,

I am a graduate student who, like all other students, went virtual in March of 2020. I've had classes, projects, and even (virtual) fieldwork in ergonomics, yet spent all day hunched over my 14 inch lap top. I finally caved in and bought some stuff. It has only been 2 days but I am so grateful for this keyboard tray! It came together very easily, and I clamped it onto my desk while in zoom class. It has a small ridge at the front which is extremely uncomfortable for your wrists/forearms, but perfect if you have a wrist wrest (as seen in the first photo) because it keeps it in place. It also has a ridge in the back to keep your keyboard and mouse from sliding off the end. I bought the 20 inch tray because I have limited space underneath my desk, and it was challenging to find a keyboard that still left enough room for the mouse. I could not seem to find any keyboards without the number pad on the right side that were not Bluetooth, overly expensive, or poorly designed. I ended buying a keyboard that is about 15 inches wide from best buy, and it leaves just enough room for the mouse. If you have room to buy the larger size tray, you will have a lot more options in terms of keyboards. I also like that the tray height is adjustable. On the highest adjustment, it leaves about 3 inches between the top of the tray and the bottom of my desk. When typing and mousing, my elbows are at a perfect 90 degree angle. I gave the sturdiness a rating of 4 because the tray sort of wobbles up and down when you move it, but it does not affect function in any way. Maybe just don't rest your elbows on it. Overall, would buy again!

Works perfect with my ergonomic keyboard and mouse pad!
