Cable management is not about stuffing all wires into a single channel. Power, signal cables, power brick size, and maintenance frequency determine the required length and partitioning.
40 cm suitable for single concentrated areas
For small desks or when there's only one power strip and a few cables, shorter trays are easier to avoid beams and drawers.
70 cm suitable for multi-device workstations
Longer trays can separate power bricks from cables, but require a more complete, flat, and clean adhesive surface. You also need to confirm the width under the desk.
Surface preparation before adhesive installation
Clean dust and oil, press firmly according to product instructions and wait; rough, damp, or easily peeling surfaces should not be assumed to be suitable.
- Test fit all devices first
- Do not obstruct ventilation
- Leave space for plugging/unplugging
Standing desks require flexible cable length
When the desktop moves up and down, there needs to be slack between the wall power outlet and the cable tray under the desk, while also avoiding creating loops that could snag feet.
Power strips and power bricks should be kept well-ventilated and used according to the manufacturer's safety guidelines; cable management does not mean you can overload connections.
