Desk
Under-Desk Slide-Out Keyboard Tray with C-Clamp Mount — 31.3 in
Product description
Important compatibility notes: This tray is designed for desks with a flat, unobstructed underside. It will not clamp securely to desks that have rounded, beveled, or curved edges, nor to tables with crossbars or support beams that block the clamp mounting. Inspect the underside of your desk before ordering.
Required clearances: The system needs a minimum of 31.3 inches of uninterrupted width under the desktop and about 11.8 inches of depth so the platform can slide in and out smoothly. Confirm these dimensions and any vertical clearance limits for taller or split ergonomic mice and oversized keyboards.
What’s in the box: The package includes the pull-out keyboard platform, dual slide rails, two adjustable C-clamps with protective pads, and the necessary mounting hardware and screws for assembly. Protective pads are provided to help prevent marring of the desk surface and to increase grip.
Construction and capacity: The platform measures approximately 25.6 x 11.8 inches of usable surface and is supported by metal slide rails. The clamp system is built to attach to tabletops up to about 1.97 inches thick without drilling. The assembly supports typical keyboard and mouse setups with a safe working load around 11 lb for steady everyday use.
How it’s used: Install the clamps on the underside of a compatible desk, attach the slide rails and platform, then slide the tray out to type and slide it back to free up work surface when not in use. The clamp design makes this a reversible, non-destructive solution for home offices, gaming desks, and shared workspaces.
Pros
- Tool-free clamp installation (no drilling)
- Large pull-out surface for keyboard and mouse
- Protective pads to prevent desk damage
Cons
- Not compatible with rounded or heavily beveled desks
- Requires significant vertical space under desk
- Limited weight capacity (around 11 lb)
VerdictA practical under-desk keyboard tray that frees desktop area and provides a comfortable typing position. The clamp installation avoids permanent alterations to furniture, the pull-out platform handles standard keyboards and mice, and the build is solid for routine use. Check desk compatibility and clearances carefully—especially for desks with beveled edges, crossbars, or shallow kneeholes—before

Better than expected — fits snugly
Extremely satisfied. My desk has a small under-lip yet the clamps still held firm. The slides are smooth and the whole assembly looks and feels high quality, almost built-in.

Nice drawer for the desk
The tray is excellent and was easy to install. It sticks out about 3 cm past my desk edge but otherwise works perfectly. I can place my keyboard comfortably.

Wanted to keep it but it didn’t fit my desk
Item is well built and easy to assemble, but it was too large for my desk so I had to return it. Quality was good and it didn’t feel flimsy.

Simple to put together, performs well
Assembly and clamping were straightforward. The tray fits my keyboard and trackball with extra room. It slides out smoothly for use and tucks back under the desk when I’m done. Very pleased with it.

Gave me back usable desktop area
My desk was getting cluttered with notes, chargers and my monitor. Moving the keyboard under the desk let me spread out papers and created much more usable space. It holds both my keyboard and mouse comfortably and is a great no-drill upgrade.

Solid construction, takes some legroom
Well made and easy to mount. The tray stays steady while I type and the slides move smoothly. It does hang fairly low, reducing leg space and lowering hand height compared to the desktop, so it took a little adjustment.

Usable surface may be smaller than advertised; diagrams confusing
Note: on furniture without a kneehole the usable flat part can be significantly shorter than the listed 11.8". Also the printed assembly diagrams don’t match the parts exactly and the screws supplied aren’t the countersunk type shown in the instructions.

Really useful and well made
Bought for a new home office. Feels solid and avoids having to drill holes. You can move it to another desk as needed. Very happy with this purchase.

Great build; fits keyboard and mouse easily
I worried it would collide with my standing desk motor, but it clears fine. A medium keyboard, mouse and pad fit with extra room. One person can assemble it—mounting the clamps near the desk edge takes a bit of effort, but otherwise all good.

Jonatan Arriaga 5/5
Durable and easy to install
The platform is sturdy and seems built to last. Slides smoothly and has room for a numpad and a small drawing tablet. Keep in mind the clamps extend about 10 cm below the desk and that dimension is fixed. Best for desks with vertical edges, though it grips minor bevels well. Easy assembly — recommended.
