Description
Adjustable Under Desk Keyboard Tray
Family: Workspace Accessories Category: Keyboard Trays Color: Black
Position the keyboard beneath the desktop with adjustable width, height, tilt and swivel. A sliding track brings the tray into use and lets it retract when space is needed at the front of the workstation.
Is This Right for You
For desks with enough clear underside depth for the track and enough knee clearance for the tray, where several keyboard-position adjustments are useful.
Key Benefits
- A sliding mouse extension changes the total working width from 465 to 645 mm.
- Tilt and swivel help orient the surface around the seated working position.
- A 300 mm track travel changes how far the tray extends from its mounting position.
Compatibility and Installation
Check the full mounting footprint against desk crossbars, drawers, control boxes and cable trays. Measure the keyboard and mouse together against the usable surface. Confirm screw length and desktop construction before fixing the track.

Materials and Construction
A powder-coated steel mechanism supports a plastic tray assembly. The mounting track transfers the tray and hand-contact forces to the desktop; sound fixing is as important as the stated equipment load.
Setup and Everyday Use
- Measure the keyboard, mouse area, underside mounting space and knee clearance.
- Fix the track using the specified mounting points and suitable screw depth.
- Set tray width, height and angle, then secure the adjustment mechanism.
- Check normal typing movement and retraction without touching the desk frame or pulling device cables.
Limitations
The 155 mm figure describes height adjustment travel; it does not mean the tray sits 155 mm below every desktop. Keep the keyboard and mouse within the 5 kg combined load. Do not use the tray to support body weight.
Package and Mounting Options
One black adjustable tray and mounting mechanism. Confirm assembly fittings in the quotation. Keyboard, mouse and desktop are not included.

Frequently Asked Questions
Does 743 mm describe the keyboard surface depth? No. It is an overall assembly dimension; the tray depth is 240 mm.
Will it fit an adjustable desk? Check the specific desk frame, control box and moving cables; desk type alone does not guarantee fit.
Is the mouse area included in the load limit? Yes. The keyboard, mouse and other supported items must remain within the 5 kg total.
