KT4 Clamp-On Keyboard Tray
Get the keyboard off your desktop without drilling into it
KT4 gives you the workspace and ergonomic benefits of an under-desk keyboard tray without making permanent holes in the desk. Clamp it to a compatible flat-edge desktop, lower the keyboard below the work surface, adjust the height and tilt, and reposition the tray later if your setup changes.
No-drill ergonomics
More than a simple clamp-on keyboard shelf
4.1-6.5 in
Lower the keyboard
Choose the keyboard height below the desktop instead of accepting one fixed position.
Neutral or negative tilt
Adjust the tray angle to fine-tune how your hands and wrists meet the keyboard.
Slide it under the desk
Tuck the keyboard away when you want more open desktop space.
Clamp on. Move later.
No drilling means the tray can move when your desk, monitors, or workspace changes.

Why clamp-on matters
Ergonomic adjustment without committing your desk to it
A practical option for desks you do not want to drill
Permanent screw-mounted trays make sense when the workstation will never change. KT4 is built for the opposite situation: home offices, shared desks, temporary setups, and workstations that may need to be rearranged later.
- No holes drilled into the desktop.
- Installs without tools on a compatible desk edge.
- Can be removed and repositioned as the workspace changes.
- Moves the keyboard below the desktop while preserving valuable work surface above.

Frequently asked questions

Will KT4 fit my desk?
KT4 is intended for compatible flat-edge desktops up to 1.25 in thick. Check the clamping edge and clear space beneath the desk before ordering.
Do I need to drill holes or use tools?

How far below the desktop can I position the keyboard?
The keyboard surface adjusts approximately 4.1-6.5 in below desktop height.
Can I adjust the keyboard angle?

Easy to install, been really nice to not have "t rex" arms at my standing desk, and very sturdy. First item came damaged from shipping but customer service was excellent and got me a replacement in no time. Really appreciate it!
