## Description

desertcart.com : VIVO Black Clamp-on 27 x 11 in Keyboard Tray, MOUNT-KB05E | Large Under Desk Keyboard & Mouse Tray for Typing, Slide Out Platform, Extra Sturdy C-Clamp Mount System, Computer Drawer : Office Products

Review: Very solid unit, easy to assemble and install - Pros: 1. Very study -- vigorous typing doesn't faze it. 2. My standard keyboard with number pad, etc., leaves plenty of room for my mouse. 3. My infrared mouse seems to work well directly on the unit's surface, which is a slightly roughened black plastic. When I had the mouse on my wooden desktop, it didn't work nearly as well -- had to use a mouse pad, which I no longer need. 4. Unit slides in and out smoothly. I was worried that it might slide too easily, but it seems to stay at whatever extended location I choose. in other word, moving it requires a bit of force -- a good thing. Cons 1. Clamps to your desk. This is easy, versatile, but not so great visually and if you do a lot of non-computer work (with the unit under the desk) you might find your arms contacting the clamps, which stick up nearly 1/4 inch above the desk top. The working space between these clamps is about 27 inches. 2. No height adjustment. It seems to be designed for a "standard" desk. It's perfect for me -- my legs fit under it easily and it's support surface is at the height of my chair's armrests. My wife's desk is lower and it definitely wouldn't work for her. Other comments 1. If your mouse and/or keyboard have cords, you'll probably want to route them somehow -- depending on where you're connecting. Prior to getting this unit, my cords went down the back of my desk and were out of the way. With the unit installed I needed to attach the cords to the underside of my desk to keep them from hanging down and getting tangled in my feet. 2. I'm hoping this will help mitigate "mouse shoulder", which was starting to bother me. (My wife points out that cutting back on video game play time might be even more effective. That will be my last resort.) So far, so good. Update after many years of use: Still working well. It did indeed cure my "mouse shoulder" problem. Two minor negatives: 1. The surface on which I rested my mouse eventually wore down to a very smooth and shiny finish, forcing me to add a mouse pad. Most of those barely fit next to a standard keyboard but I found something that works. 2. I would really like some way to lock it in the extended position. It extends and retracts so easily that I find myself having to keep pulling it back out, especially during gaming when I need it to be stationary.
Review: excellent build quality - My VIVO MOUNT-KB05E keyboard works great. The build quality is excellent. I didn't want to drill into my new desk, so this clamp-on solution is perfect for me. The clamps are low-profile (flat) on the top of the desk, and far enough wide apart so that they wouldn't get in my way much even if they were taller. A minor cosmetic issue: The flat keyboard tray itself comes in two pieces. The two pieces are easy to connect together using a screwdriver on the included brackets and the result is solid, but there is a visible line between the pieces. Not a big deal, but I wish it was a single piece tray shipped in a longer box to eliminate the line and to be less work for customers when building. Before I purchased, the product information warned that a full 12 inches of clearance is required under the desk. That's true in the tray's regular configuration, but in the instructions that came with my tray, it explains there are additional screw holes for an "extended" configuration where the tray sticks out a little (about an inch and a half) in front of the desk when the tray is fully closed. I use the extended configuration which was a relief because I knew my Branch brand Office Desk only had 11 inches of clearance under there and I was worried about the tray not fitting. The product information also warns not to use this tray with a beveled-edge desk. My desk has about a half-inch bevel, which works fine with the clamp pads for the VIVO tray, so that's another issue I was worried about that turned out to be fine. Any more than half an inch of bevel looks like it would start to cause problems because the clamps need enough flat desk to press against. On my desk the clamp pads are just at the edge of the half inch bevel so I lucked out.

## Questions & Answers

**Q: With just clamps on the edge, I'm worried about the stability. If I rest my hands on it or pushes it bit down, would it be stable and not wobbly?**
A: I had the same worry, but it's a heavy duty product. Very well made and very stable. I rest my hands on it and type (fast and a lot) with no issues. It glides smoothly under my desk and is wide enough for my giant ergnomic keyboard, mouse, and mousepad (with a tiny bit of room to spare). I am very pleased with it and would buy it again.

**Q: does the tray lock in position?**
A: no, the tray slides in and out. Push in when not in use and slide out when needed. It stays in place nicely and does not move when you slide it to your desired position.

**Q: What is the minimum distance required under the desk for the screw-part of the clamp? I have a maximum of 1-3/4 inches before a piece of wood.**
A: Not sure about your question, but my desk edge thickness is 1.5", and the bracket with the screw clamp extends 3.5" below the bottom of the desk edge.

**Q: Will this be able to be mounted at an angle for a corner desk?**
A: Hello,

Thank you for your interest! No, this mount is only recommended to be used on a straight edge desk. Please let us know if you have any further questions. We are always happy to help.

Thank you,

### ⭐⭐⭐⭐ Minor fixes made this perfect for my use.
*by I***K on November 24, 2025*

This is a nice keyboard tray. There is a known issue of the tray walking away from you as you type. My fix was to purchase a Barrel Bolt Latch and mount it on each side to keep the tray from doing that. The extended pin prevents it from walking. Had this come with something like that, they'd have gotten five stars. The width accommodates my keyboard and my rollerball mouse, along with a wrist rest for each. My desk is a lesser cost up/down desk so I needed to take into consideration the measurement of the space allotment under the desk so it didn't interfere with the up/down drive pin. This works and I can move the keyboard at a whim, not locking me into a specific position at the desk. Value for the money I think is very fair. Drill accuracy was good, very easy to assemble. The ease of use is great. Put a lock mechanism into play on this and you have a great tray. I am very well pleased with this set-up. I don't need the tray to tip forward as the pad I have it on does this. I adjust the height of the desk for ccommodating my wrist/hand tilt. Ergonomic perfection? Nop[e. But it works for me.
