Middle Atlantic CUS RACKSHLF5SP Anod 17.5 - RSH4A5X

Middle Atlantic RSH4A5X 5U Rackmount Steel Shelf

Overview

The Middle Atlantic RSH4A5X is a 5U, 17.5-inch (445 mm deep, 482.6 mm wide) steel rackmount shelf built for integrators who need a reliable horizontal surface inside a standard 19-inch equipment rack. Whether you're staging NVRs, unmanaged switches, cable management panels, or ancillary AV gear that doesn't mount natively to rack rails, the RSH4A5X gives you a flat, sturdy platform with a footprint sized for real-world rack density.

Finished in black anodized steel, the shelf fits cleanly into commercial enclosures and equipment racks used across surveillance, AV distribution, and network infrastructure installations. At 5U tall, it provides enough vertical clearance to stack equipment that ships without rack ears — a common requirement when deploying third-party hardware in a managed rack environment.

Key Features

• 5U Rack Height (222 mm): Five rack units of vertical clearance means you can seat a compact NVR, an unmanaged PoE switch, or a stack of smaller appliances without the shelf becoming a wasted bay. If your rack is running tight on U-space, this depth of clearance forces you to think carefully about what goes on it — plan accordingly.
• 17.5-Inch Width / 482.6 mm Rack Fit: The 482.6 mm width aligns with the EIA-310 19-inch rack standard, so this shelf drops into any standard two-post or four-post rack without shimming or custom hardware. No surprises on-site.
• 445 mm Usable Depth: At roughly 17.5 inches of depth, this shelf accommodates most 1U and 2U appliances that ship without ears — including mid-depth NVRs and access control servers that max out around 400 mm. Measure your deepest non-rack-mount device before selecting; anything past 445 mm will overhang.
• Steel Construction: Steel over aluminum means the shelf handles the static load of dense equipment without flexing — relevant when you're resting a 4–6 kg NVR on an unsupported span inside a wall-mount enclosure. The material also takes paint and anodizing uniformly, giving you a clean install inside a client-visible rack.
• Black Finish: The black finish matches standard Middle Atlantic rack enclosure interiors and most third-party rack systems, keeping the installation looking consistent — a small detail that matters in client-facing deployments like reception area racks or board room AV panels.
• Single-Unit Pack (1 pc): Ships as a single shelf unit, which is the correct quantity for most single-bay deployments. If you're populating a multi-bay rack, order per shelf count — there's no bulk-kit SKU in this configuration.

Integration & Compatibility

The RSH4A5X is sized to the EIA-310 19-inch rack standard at 482.6 mm wide, making it compatible with standard two-post open frame racks, four-post closed cabinets, and Middle Atlantic's own rack enclosure systems. Integrators deploying Middle Atlantic rack systems will find the shelf dimensions align directly with their existing enclosure footprints.

This shelf is a passive mechanical component — it requires no power, carries no signal, and introduces no network dependency. That means compatibility is determined entirely by your rack's width (19-inch standard required) and the depth of the equipment you intend to place on it (445 mm max). For any NVR, PoE switch, or appliance landing on this shelf, consult the parent rack accessories category for complementary cable management and power distribution options that pair well with this shelf.

Integrators designing structured rack builds should also review a PoE switch lineup if this shelf is intended to seat a switch for downstream camera power — matching switch depth to the 445 mm shelf clearance is the first constraint to verify.

Frequently Asked Questions

Q: What rack standard does the RSH4A5X fit?

A: The RSH4A5X is 482.6 mm wide, which matches the EIA-310 19-inch rack standard. It fits any standard two-post or four-post 19-inch rack.

Q: How deep is the RSH4A5X shelf surface?

A: The shelf is 445 mm (approximately 17.5 inches) deep. Equipment mounted on it should not exceed this depth to avoid overhang.

Q: How many rack units does the RSH4A5X occupy?

A: It occupies 5U of vertical rack space (222 mm total height).

Q: What material is the RSH4A5X made from?

A: The shelf is constructed from steel and finished in black.

Q: Does the RSH4A5X come with mounting hardware?

A: Package contents beyond the single shelf unit (1 pc) are not confirmed in available evidence. Verify with the seller before ordering if rack-mount screws are required separately.

Q: Is the RSH4A5X sold as a single unit or in a multi-pack?

A: The RSH4A5X is sold individually — quantity per pack is 1 pc.
