Middle Atlantic 2 Space Custom Rackshelf 11.5IN. Deep Black Anodized Finish - RSH4A2S

Middle Atlantic RSH4A2S 2U Custom Rackshelf 11.5-Inch Deep Black Anodized

Overview

The Middle Atlantic RSH4A2S is a 2U (89mm tall) fixed rack shelf designed for standard 19-inch EIA racks — the kind of no-fuss, load-bearing platform that integrators reach for when a component doesn't have its own rack ears but still needs a permanent home in an equipment cabinet. At 11.5 inches (292mm) deep and 482.6mm wide, the RSH4A2S fits any standard rack column without modification. The steel construction with black anodized finish means it won't flex under moderate gear loads and blends cleanly into professional rack builds — no raw edges, no paint chips over time the way cheaper powder-coat shelves develop.

Whether you're racking a NVR without ears, a cable modem, a media converter shelf, or a small UPS, the RSH4A2S gives you a clean 2U footprint with enough depth to handle most mid-size equipment without the shelf hanging awkwardly past the rack's rear rails.

Key Features

• 2U form factor (89mm height): Two rack units consumed means you're not sacrificing three or four U's for a single non-rack-mount device — every U in a populated cabinet costs real money in terms of what else you can't fit. Two U is the practical minimum for most shelf applications without cramping airflow above and below.
• 11.5-inch depth (292mm): Deep enough to support full-depth equipment like compact NVRs, network appliances, and AV gear without tipping risk, yet shallow enough that it won't interfere with rear cable management or mid-mount vertical PDUs in standard 24-inch-deep cabinets.
• 482.6mm width — full EIA 19-inch standard: Mounts directly to any standard 19-inch rack or enclosure without adapters. If your rack columns are EIA-310 compliant, this shelf drops straight in.
• Steel housing: Steel outperforms aluminum shelves on static load capacity and doesn't deform under sustained weight the way thin aluminum can in warm equipment rooms. For rack builds that stay populated for years without maintenance cycles, steel is the right call.
• Black anodized finish: Anodizing is a surface hardening process, not a coating — it doesn't peel, chip, or flake the way spray paint or powder coat does under rack vibration or repeated cable contact. The black finish also maintains consistent rack aesthetics when mixed with other Middle Atlantic rack products.
• Single-unit pack quantity: Sold individually, so you're buying exactly what you need per rack position — no surplus hardware sitting on the shelf when a two-pack doesn't match your deployment count.

Integration and Compatibility

The RSH4A2S is built to EIA 19-inch rack standards (482.6mm width), making it compatible with the full range of standard open-frame racks, enclosed cabinets, and wall-mount enclosures that follow EIA-310 column spacing. It pairs naturally with other Middle Atlantic rack infrastructure — relay racks, vented side panels, cable managers — as part of a coordinated rack build.

For security integrators, this shelf is a common solution for housing equipment alongside network video recorders or PoE switches that ship without rack ears. Rather than using field-fabricated brackets or zip-tying gear to the rack frame, a proper shelf like the RSH4A2S keeps the installation serviceable and the rack organized for the long term.

The 292mm depth accommodates most half-depth networking gear and compact security appliances. Verify the depth of your specific equipment before ordering if you're working with full-depth 1U servers or deep UPS units — this shelf is sized for mid-range equipment, not full-depth data center hardware.

Frequently Asked Questions

Q: What rack standard does the RSH4A2S fit?

A: The RSH4A2S is 482.6mm wide, which matches the EIA 19-inch rack standard (EIA-310). It mounts directly to any standard 19-inch open-frame rack, enclosed cabinet, or wall-mount enclosure with EIA-compliant column spacing.

Q: How many rack units does the RSH4A2S occupy?

A: The RSH4A2S occupies 2U (89mm of vertical rack space).

Q: How deep is the RSH4A2S shelf surface?

A: The usable shelf depth is 11.5 inches (292mm), suitable for compact NVRs, media converters, small network appliances, and similar mid-depth equipment.

Q: What material and finish does the RSH4A2S use?

A: The shelf is constructed from steel with a black anodized finish. Anodizing is a hardened surface treatment that resists chipping and peeling over time, unlike painted finishes.

Q: Does the RSH4A2S come with mounting hardware?

A: Package contents are not specified in available product data. Contact your supplier to confirm whether cage nuts and rack screws are included or need to be ordered separately.

Q: Is the RSH4A2S sold individually or in a multi-pack?

A: The RSH4A2S is sold as a single unit (quantity per pack: 1).
