StarTech CABSHELF1U10 1U 19in Server Rack Cabinet Shelf, 10in Deep

Overview

The CABSHELF1U10 is a 1U fixed rack shelf built to carry non-rackmount gear — switches, small NVRs, UPS units, patch equipment, or any device that doesn't ship with its own rail kit — inside a standard 19in EIA/ECA-310-E cabinet. StarTech built this one shallow: 9.8in of product depth versus the 12-16in shelves common in this category, which matters if you're working in a shallow wall-mount or half-depth floor cabinet where a deeper shelf either won't clear the door or leaves the mounted equipment hanging unsupported past the shelf edge. At 1U of vertical space consumed, it's a compact way to reclaim rack real estate for equipment that would otherwise eat a lot more room sitting loose on top of the cabinet.

Key Features

• 44.1 lb (20 kg) weight capacity: enough to carry a small NVR, a desktop switch, or a compact UPS without stressing the shelf — check your heaviest planned device against this ceiling before you buy, since it's a hard limit, not a rating with headroom built in.
• 9.8in product depth: a genuinely shallow shelf, which is the whole reason to pick this model over a standard-depth alternative — it fits cabinets where a deeper shelf would interfere with the door or leave equipment unsupported.
• 17.4in internal width: matches standard 19in rack rail spacing, so it drops into any EIA/ECA-310-E compliant cabinet without adapter brackets.
• 1U height (1.7in): consumes minimal vertical space in the rack, which counts when every U is already spoken for by switches, patch panels, and NVRs.
• Steel frame and construction: holds up under sustained equipment load and repeated add/remove cycles better than stamped aluminum shelving, at the cost of the 4.4 lb (2.0 kg) the shelf itself adds to your rack's total load.
• EIA/ECA-310-E compliance: the shelf mounts using the same hole spacing and standard as the rest of your rack hardware, so it integrates with cabinets from any manufacturer built to that spec — no proprietary mounting system to work around.
• Black finish: matches the finish convention used across nearly all commercial rack hardware, so it doesn't stand out visually against switches, patch panels, and NVR enclosures already installed.
• Lifetime warranty: covers a component with no moving parts and no firmware — the kind of hardware where a long warranty term is actually meaningful, since failure modes are limited to the steel itself.

Integration & Compatibility

Because the CABSHELF1U10 follows EIA/ECA-310-E, it installs in any standard 19in rack or cabinet — this isn't a proprietary system tied to one enclosure line. That makes it a straightforward add when you're populating a rack with a mix of rail-mount and non-rail equipment: run your network video recorders and switches on rails where they support it, and drop the CABSHELF1U10 in for anything that doesn't. If you're planning out a full rack build from scratch, a PoE planning guide is worth reviewing before you finalize U-space allocation, since shelf-mounted gear and PoE switch port budgets both compete for the same rack footprint. For the switching gear that typically ends up sitting on a shelf like this, check the network switches category for PoE and non-PoE options sized to fit. The shallow 9.8in depth is the deciding spec here — measure your cabinet's usable depth before ordering, since a shelf that's too deep for the enclosure is the most common return reason in this product category.

Frequently Asked Questions

Q: What's the weight capacity of the CABSHELF1U10?

A: 44.1 lb (20 kg). Stay under this limit — it's a hard ceiling on a fixed steel shelf, not a rated-with-headroom figure.

Q: How deep is the CABSHELF1U10?

A: 9.8in (25 cm) of product depth, with a total product width of 18.3in and height of 1.7in (1U). This is a shallow-depth shelf, designed for cabinets where standard 12in+ shelves don't fit.

Q: Will the CABSHELF1U10 fit a standard 19in rack?

A: Yes. It has a 17.4in internal width and is built to EIA/ECA-310-E, the standard governing 19in rack rail spacing, so it fits any compliant cabinet.

Q: What's the warranty on the CABSHELF1U10?

A: Lifetime warranty from StarTech.

Q: What is the CABSHELF1U10 made of?

A: Steel frame and construction, finished in black, weighing 4.4 lb (2.0 kg) on its own.

The spec that gets buyers on the CABSHELF1U10 is the 9.8in depth — most 1U shelves on the market run 12-16in deep, and that difference is exactly what determines whether this thing fits your cabinet or gets returned. If you're working a shallow wall-mount enclosure or a half-depth floor cabinet, this is the one to check first.

Technical Highlights:

• 44.1 lb (20 kg) capacity: covers a compact NVR, an 8-24 port desktop switch, or a small UPS — I wouldn't push much past that on a fixed 1U shelf regardless of the rated number.
• 17.4in internal width on a 1U (1.7in) profile: full standard rail spacing without burning more than one U of rack space — efficient if you're tight on U count in a smaller cabinet.
• Steel construction at 4.4 lb (2.0 kg) shelf weight: that's dead weight added to your total rack load calculation, but it buys sag resistance under a loaded switch or UPS that stamped aluminum shelving doesn't hold up as well under long-term.

Deployment Considerations:

• Measure your cabinet's actual usable depth before ordering — the whole value proposition of the CABSHELF1U10 over a standard shelf disappears if your enclosure is already deep enough to take a bigger unit.
• This is a fixed, non-sliding shelf — there's no pull-out or vented design implied by the spec sheet, so plan equipment placement and cable routing before you set it in the rack, not after.

Where this earns its spot: a shallow wall-mount cabinet in a network closet or small server room where you need to rack-mount a switch or small NVR that has no rail ears of its own, and a standard-depth shelf simply won't clear the door.
