G.Sumiker extra-large ventilated clamp-on steel tray

The largest tray surface in this hub at 13.38 by 7 in, ventilated and open-grid, mounted by adjustable no-drill brackets — and the only American tray here that publishes no weight figure.

G.Sumiker extra-large ventilated cable tray clamped under a desk holding a power strip and adapters

G.Sumiker extra-large ventilated clamp-on steel tray

  • A 13.38 by 7 in surface, the largest tray floor here after the KabelZen's 66 × 24 cm mounting panel — where a strip plus its slack actually fits
  • Open-grid, ventilated construction rather than a closed trough
  • No weight capacity published anywhere on the listing — the figure the other three American trays here all state

Best for: A desk with a power strip and several bulky adapters that need air around them.

This hub’s first comparison is whether a tray is sized for an entire power strip plus the slack of several cables, rather than for cables alone. At 13.38 by 7 in this is the largest tray floor on the shelf — only the KabelZen’s flat 66 by 24 cm mounting panel is bigger — and the surface is well over the 3 to 5 in depth of the shallow trays here, and the grid is open rather than troughed, so a strip with four molded adapters hanging off it has air round all of them.

The mounting is tool-free, with adjustable brackets for tops between 0.4 and 2 in and a stated 60-second setup. That is a narrower range than the 0.4 to 2.4 in clamp alongside it, which is worth knowing against the bullet that promises it will “fit all standing desks, L-shaped workstations, and office furniture” — a thick butcher-block top over 2 in is outside the published range whatever the bullet says.

Two things are missing and one is odd. There is no weight capacity on the page at all, in a hub that compares it and on a tray explicitly sold to carry power strips. There is no clamp fatigue statement, which no tray here provides. And one of the five bullets argues that the tray “helps keep flammable cables away from direct contact with heat sources, further reducing fire risks” — a sentence about what else is under your desk rather than about the product, in a listing that elsewhere publishes its surface, its bracket range and its finish.

What holds up, and what does not

Best for: A desk with a power strip and several bulky adapters that need air around them.

Strengths

  • A 13.38 by 7 in surface, the largest tray floor here after the KabelZen's 66 × 24 cm mounting panel — where a strip plus its slack actually fits
  • Open-grid, ventilated construction rather than a closed trough
  • Tool-free adjustable brackets for tops from 0.4 to 2 in, stated to set up in 60 seconds
  • Integrated cable ties, and access from all round rather than through one opening
  • Smooth edges, which the listing calls out specifically for handling cables

Compromises

  • No weight capacity published anywhere on the listing — the figure the other three American trays here all state
  • At 7 in deep it takes more room under the desk than the 3 to 5 in trays here, so check knee clearance
  • Claims to "fit all standing desks" while publishing a narrower clamp range (0.4 to 2 in) than the Cinati (0.4 to 2.4 in)
  • One safety bullet argues the tray reduces fire risk by keeping cables away from heat sources, which is a claim about your desk rather than about the tray

What buyers ask us first

How much will it hold?

G.Sumiker does not publish a figure. The listing calls the tray "heavy-duty steel" with a "Spacious & Durable Design" and states that "Its sturdy construction ensures that it won’t easily tip or break, keeping your power strips and cords stable" — all of which is about construction rather than load. The three other American trays in this hub state 10, 11 and 15 lb.

Does the open grid matter?

For a power strip with several plug-in adapters in it, yes. A closed trough holds warm air around the transformers; an open grid lets it out, which is why the listing pairs "ventilated design prevents overheating" with the extra-large surface. The cost is that everything inside is visible from below and dust settles through it rather than in it.
