Put the power strip on the desk, not on the floor. Screwed or clamped into a tray under the desktop, the strip moves with the desk, so every cable between it and the monitor, laptop or lamp stays the same length whatever the height. Only one cable — the strip’s own — then has to travel down to the wall. The under-desk cable trays hub compares sizes, load ratings and fixings.
Leave slack for the full height range. Raise the desk to its highest setting before fixing anything, and route the cables from desk to floor with a gentle curve at both ends. Then lower it to the bottom and check that the slack folds away without catching on the frame or the chair. A cable pulled taut at the top setting strains the plug every time the desk rises.
Gather the drop to the floor in one run. A split cable sleeve keeps the power and network cables together as one loose bundle that bends as the desk moves, and opens along its length so a cable can be added later. The cable management hub includes sleeves, clips and raceways.
Bundle loosely, not tightly. Hook-and-loop straps or a sleeve should hold cables together without cinching them; a bundle pulled tight cannot flex, and the stress ends up at the connectors.
Prefer a screwed tray on a desk that moves daily. A clamp holds by pressure, and none of the clamp-on trays on this site states a rating for repeated height changes. Screws have nothing to loosen. On a desk you cannot drill, use a clamp and check it after the first weeks.
Re-check after a week. A route with borderline slack usually shows itself only after a few dozen cycles: look for a cable rubbing the frame or a plug starting to pull out of its socket.
What buyers ask us first
Can I use the same cable tray I'd use on a fixed desk?
Yes, but think about the fixing. None of the clamp-on trays in this site's under-desk tray hub states that its clamp is rated for daily height changes, so on a desk that moves every day a screwed tray — the COYACOOL, for instance — has nothing to work loose. A clamp-on tray suits a desk you cannot drill, checked after the first weeks.
How much slack should I leave in each cable?
Enough that every cable stays gently curved with the desk at its highest setting. Measure from the desktop to the floor outlet at full height; that is the length the drop has to cover, plus a loop at each end.
What goes in the sleeve?
Only the cables that run from the desk to the floor or the wall — power and network, usually. Everything that stays on the desk stays in the tray. A split sleeve such as the Alex Tech, 10 ft of 1/2 in, lets cables be added or removed later without unplugging the rest.
