Under-Desk Pull-Out Keyboard Tray with C-Clamp — Slide-Out Keyboard & Mouse Platform

Product description

Check desk underside before ordering — this clamp-mounted keyboard tray requires a flat, unobstructed bottom surface and will not attach securely to desks with rounded, beveled or curved edges, or with crossbars or support beams beneath the top.

Allow for clearance: the assembly needs at least 31.3 inches of horizontal room beneath the tabletop and about 11.8 inches of forward depth for the platform to slide in and out without interference. Confirm those measurements and any obstacles under your work surface before purchase.

What’s included: the pull-out keyboard platform (25.6 x 11.8 in), two sliding metal rails, adjustable C-clamp mounting hardware with protective pads, fasteners and a short instruction leaflet. The clamp system fastens to tabletops up to 1.97 inches thick without drilling or permanent modification.

Construction and capacity: the tray platform is designed to hold a standard keyboard and mouse and is supported by sturdy metal rails. Protective clamp pads help prevent scrapes on the desktop and improve grip. The mounting assembly is rated for everyday use up to 11 lb; check dimensions and the height of tall vertical mice, oversized keyboards or split ergonomic layouts before fitting.

How it’s used: slide the platform out to type or use the mouse, then slide it back under the desk to restore clear work surface area for monitors, paperwork or drawing. Ideal for office desks, home workstations and gaming setups where saving tabletop real estate and improving wrist posture are priorities.

Pros

  • No-drill C-clamp installation protects the desk
  • Large 25.6 x 11.8 in platform fits standard keyboard and mouse
  • Smooth sliding rails and solid everyday stability

Cons

  • Requires flat underside and enough clearance — not for beveled edges
  • Occupies noticeable vertical space under the desk
  • Limited load capacity at 11 lb

VerdictA practical, no-drill keyboard tray that reclaims surface area and keeps keyboard and mouse stored neatly beneath the desktop. The metal sliding rails and clamp mounting offer a sturdy feel and smooth operation for everyday typing and casual gaming, but it uses notable vertical space under the desk and requires a flat underside to attach the clamps.

Reader reviews

  1. Robert Tillman 5/5

    Better than expected

    Fits snugly under my desk lip and feels very secure. Slides and looks high quality, like it belongs with the desk. Highly pleased with the result.

  2. marie-issa 5/5

    Desk drawer works well

    I installed it easily; one minor issue is it protrudes 3 cm from my desk but otherwise it’s perfect and holds my keyboard comfortably.

  3. TL 5/5

    High quality but didn’t fit my desk

    I had to return it because my desk was too small, but the build felt solid and it was easy to assemble.

  4. C Gilbert 5/5

    Simple to set up, performs well

    Assembly and mounting were straightforward. The tray fits my full keyboard and trackball with extra room and slides smoothly in and out. Very satisfied with the purchase.

  5. angirojas02 5/5

    Freed up a lot of desk space

    My workspace was cluttered and this tray made a big difference. Keyboard and mouse tuck away so I can spread out papers or write. Clamp mounting was ideal since I didn't want to drill holes.

  6. Katie 4/5

    Well built and steady

    Good materials and easy to attach. Typing feels stable with no wobble and the sliding action is smooth. It does sit lower than my old setup, so legroom is reduced and it took a little getting used to.

  7. Alvaro 5/5

    Extremely practical and well made

    Robust and very useful, especially for gaming. Easy to install and better than I expected. Great value and quality.

  8. Ed8r 3/5

    Usable surface can be much smaller than listed

    On my armoire the usable flat area under the lip was only about 7 in instead of the advertised 11.8 in. Also note that the included diagrams and some fasteners didn’t match the pieces I received.

  9. Massimo 5/5

    Very useful and attractive

    Bought it for my new home office. It’s solid and avoids drilling holes, so you can reposition it as needed. Very happy with the product.

  10. Marcos Daniel 5/5

    Very good product

    It didn’t interfere with my standing desk motor. A medium keyboard, mouse and pad fit with room to spare. One person can assemble it but attaching the clamps is the trickiest part.

  11. Jonatan Arriaga 5/5

    Durable and easy to install

    The platform is very sturdy and the glide works smoothly. It has enough room for a numeric keypad and a small drawing tablet. Keep in mind the clamps extend about 10 cm below the desk and aren’t adjustable; best for desks with straight vertical edges.
