Middle Atlantic 4 Space Custom Rackshelf 14IN. Deep Anodized Black Finish - RSH4A4M

Middle Atlantic RSH4A4M 4U Steel Rack Shelf, 14-Inch Deep, Anodized Black

Overview

The Middle Atlantic RSH4A4M is a 4U rack shelf built for integrators who need a solid, fixed-depth mounting surface inside a standard 19-inch equipment rack. At 14 inches (356 mm) deep and spanning four rack units of vertical space, it gives you enough room to seat mid-sized components — think NVR chassis, media converters, UPS units, or ancillary security appliances — without the guesswork of a shallow shelf that leaves equipment hanging over the edge. The anodized black steel finish matches the interior of most black rack enclosures and resists surface wear in environments where panels get opened and closed repeatedly.

Key Features

• 4U Rack Height (178 mm): Four rack units of vertical clearance means you can seat taller components — 2U NVR chassis, stacked converters, or appliances with top-mounted connectors — without fighting for space above the shelf surface. If your rack plan is tight, count your U budget before ordering.
• 14-Inch Depth (356 mm): The 356 mm deck handles most mid-depth security appliances without overhang. Components deeper than 356 mm will need a deeper shelf or a different mounting solution — verify your equipment's chassis depth before specifying.
• Full-Width 19-Inch Mounting (482.6 mm): Spans the standard EIA-310 19-inch rack width, so it drops into any compliant open-frame, enclosed, or wall-mount rack without shimming or adapter brackets.
• Steel Construction, Anodized Black Finish: Steel provides a stable, non-flexing deck surface — important when you're resting equipment that generates vibration or has bottom-mounted ventilation. The anodized finish holds up to routine handling better than painted alternatives that chip at rack edges.
• Single-Unit Pack Quantity: Ships as one shelf per pack, which simplifies per-rack line-item budgeting on multi-rack deployments. Order exactly as many as your rack layout requires.

Integration & Compatibility

The RSH4A4M fits any standard 19-inch rack enclosure or open-frame rack that conforms to EIA-310 spacing. The 482.6 mm width and standard rack-unit hole pattern align with Middle Atlantic enclosures as well as third-party racks from other manufacturers. When specifying for a network video recorder or similar security appliance, confirm that the NVR chassis depth does not exceed 356 mm and that the unit's weight falls within the shelf's load rating — consult the Middle Atlantic datasheet or your rack enclosure's documentation for verified load figures. Pair with a compatible rack power distribution unit to complete the installation.

Frequently Asked Questions

Q: What rack form factor does the RSH4A4M fit?

A: The RSH4A4M is designed for standard 19-inch EIA-310 equipment racks. Its mounting width is 482.6 mm, which aligns with the standard 19-inch rack hole pattern used in open-frame and enclosed rack enclosures.

Q: How deep is the RSH4A4M shelf deck?

A: The shelf deck is 356 mm (14 inches) deep. Equipment with a chassis depth greater than 356 mm will overhang the front edge; verify your component's depth before specifying this shelf.

Q: How many rack units does the RSH4A4M occupy?

A: The RSH4A4M occupies 4U (four rack units), which corresponds to a height of 178 mm. Plan accordingly in your rack unit budget before ordering.

Q: What material and finish does the RSH4A4M use?

A: The shelf is constructed from steel with an anodized black finish, providing a stable deck surface and durable surface treatment suited for repeated handling in active equipment racks.

Q: How many shelves are included per order?

A: Each order of the RSH4A4M includes one (1) shelf unit. Order the quantity that matches your rack layout requirements.
