Middle Atlantic CUS Rckshlf 1SP Anod 8 - RSH4A1XS

Middle Atlantic RSH4A1XS 1U 19-Inch Rack Shelf

Overview

The Middle Atlantic RSH4A1XS is a 1U, 19-inch rack shelf built from steel and finished in black anodized aluminum — a straightforward, no-moving-parts solution for staging lightweight components inside a standard EIA rack enclosure. If you are fitting out a rack enclosure and need a fixed, tool-accessible surface for a media converter, small switch, or accessory device that does not have its own rack ears, this shelf handles that without requiring a custom bracket. The RSH4A1XS occupies a single rack unit and provides 203.2 mm (approximately 8 inches) of usable depth, which fits most compact appliances without pushing into cable management space in the rear.

Key Features

• 1U Form Factor (48.3 cm / 19-inch EIA standard): Fits any standard 19-inch rack rail without modification — no custom hardware, no adapter kits. One rack unit consumed means minimal impact on enclosures where space is already planned tight.
• 203.2 mm (8-inch) Shelf Depth: Shallow enough to leave rear cable management lanes clear in mid-depth enclosures, yet sufficient for media converters, fiber patch panels, small UPS accessories, and similar compact hardware that lacks native rack mounting.
• Steel Construction with Black Anodized Finish: Steel provides the load stability expected in a commercial rack environment. The anodized finish resists corrosion and handles the heat cycling common in enclosed rack cabinets better than painted surfaces that can chip or outgas over time.
• Single-Pack Quantity: Ships as a single unit — size your order to the actual number of open slots in your rack rather than buying in bundles you do not need.

Integration & Compatibility

The RSH4A1XS is designed for standard EIA 19-inch rack rails at 482.6 mm width. It is a passive component — no power, no data connections — so it integrates into any network cabinet or rack enclosure that follows the 19-inch standard regardless of manufacturer. Pair it with rack accessories such as cable managers or blanking panels to complete your enclosure build. For deeper components or higher load requirements, review other shelf options in the Middle Atlantic rack product line before committing to this model.

Frequently Asked Questions

Q: What rack standard does the RSH4A1XS fit?

A: The RSH4A1XS is designed for standard 19-inch EIA rack rails (482.6 mm width), which covers the vast majority of commercial rack enclosures.

Q: How much depth does the RSH4A1XS provide?

A: The shelf provides 203.2 mm (approximately 8 inches) of usable depth — suitable for compact appliances, media converters, and similar low-depth accessories.

Q: How many rack units does the RSH4A1XS occupy?

A: It occupies 1U (one rack unit), minimizing the impact on overall rack space planning.

Q: What material is the RSH4A1XS made from?

A: The shelf is constructed from steel with a black anodized finish for durability and corrosion resistance in enclosed rack environments.

Q: Does the RSH4A1XS include mounting hardware?

A: Package contents beyond the shelf unit itself are not confirmed in available evidence. Verify with your order documentation or contact pre-sales engineering for confirmation.

The RSH4A1XS is one of those components that does not get much attention until it is missing from the build list — at 1U and 203.2 mm deep, this Middle Atlantic shelf fills the specific gap of housing non-rack-ear accessories in a standard 19-inch enclosure without wasting space or requiring fabricated solutions.

Technical Highlights:

• 1U Steel Construction: Steel at 1U provides a stable load platform without consuming the extra rack space that 2U utility shelves waste in tight enclosures — relevant when you are counting units in a fully planned rack.
• 482.6 mm Rail Span: Matches EIA 19-inch rack rail spacing exactly, so no shimming, no adapter brackets, and no lateral slop that causes alignment problems with adjacent patch panels or switches.
• 8-Inch Depth (203.2 mm): Shallow profile keeps rear cable management lanes accessible — a practical advantage in any enclosure where cable routing is done post-installation rather than pre-planned.

Deployment Considerations:

• Verify the weight rating before placing heavy appliances — available evidence does not include a published load capacity for the RSH4A1XS, so confirm with Middle Atlantic documentation for anything beyond light accessories.
• At 8 inches of depth, this shelf will not accommodate full-depth appliances or 1U servers — for anything deeper than 200 mm, a longer shelf model from the Middle Atlantic line is the correct choice.

The RSH4A1XS is well-suited for security rack builds where you need to stage a media converter, fiber transceiver chassis, or small accessory device inside a structured rack enclosure — specifically in deployments where rack space is already allocated tightly and a 2U shelf would break the layout.
