Product description

A cleaner desk, a healthier you. Whether sitting or standing, this under desk keyboard tray brings your workspace to where you are—freeing up the surface above and keeping you comfortable all day.

Get set up in minutes, not hours. Just turn the knob to clamp securely onto any desktop from 0.3″ to 1.96″ thick—no drill, no hassle.

Slides away when you don’t need it—only 11.8” of depth required to tuck neatly under your desk. With a total width of 31.7” including clamps, it fits comfortably without crowding your legs or chair arms.

Made for corner desks. The dual clamps rotate up to 60°, so you can finally put that awkward L-shaped corner to work. No more wasted space—just a perfectly placed keyboard tray where you need it.

Glides out smooth, stays put while you type. Built with 48 precision steel balls, the track moves silently and effortlessly—and locks down tight so your keyboard never shakes or shifts under your fingers.

Engineered for zero-wobble stability during intense typing sessions, this under desk keyboard tray stays firmly in place when you need it and slides smoothly when you don’t.
