A tray holds a power strip and its cable slack, not just wires in a channel

The best under-desk cable trays for 2026

A cable tray does a different job than a thin adhesive channel — it is sized to hold an entire power strip along with the slack of several device cables, mounted below the desktop where none of it is visible from a seated position. We compare capacity for a full power strip plus slack, clamp mounting security specifically on an electric standing desk that moves height daily (a tray that only grips a fixed desk edge can work loose on one that raises and lowers), and depth for keeping cables from dragging on the floor.

What we recommend

Who each type suits

Visible desk: A workstation in the middle of a room shows everything that hangs. The tray is what makes it presentable.
Sit-stand desk: A tray fixed to the top rises with it. The only way to manage cables on a desk that moves.
Cleaning: A clear floor is cleaned in one pass. The most everyday and most underestimated benefit.

The trade-offs to weigh

Screwed against clamped: A screwed tray carries any load and drills the top; a clamped tray drills nothing, carries less and needs an accessible edge.
Closed tray against open basket: A closed tray is tidier and makes reaching the cables awkward; an open basket lets you see and is changed in a moment.
Capacity against legroom: A deep tray swallows everything and descends into the knee space. Its position under the top counts as much as its size.

Questions buyers ask

Does the top have to be drilled?

Screwed models hold best; clamp or adhesive models avoid drilling and carry less load.

Where should the tray go?

At the back of the top, out of the knee space. A tray set too far forward gets in the way as soon as you cross your legs.

Does the power strip fit inside?

That is the main use, provided the width is enough. Check your strip's dimensions first.

Do the cables heat up inside?

A tight bundle around a power supply under load runs hotter. A perforated basket ventilates better than a closed tray.

Can it go on an adjustable desk?

That is in fact the right configuration: fixed to the top, it rises with it and removes the strain on the cables.

How do I get the cables down to the floor?

Through a vertical sleeve along a leg, guiding the remaining bundle. That is what completes the installation.

What load does a tray carry?

A power strip and cables, not a heavy computer power brick. Screwed models carry distinctly more.

What to remember

The tray goes at the back of the top, out of the knee space — set too far forward it gets in the way as soon as you cross your legs. Fixed to the top on an adjustable desk, it removes the strain on the cables, and a perforated basket ventilates better than a closed tray.
