Middle Atlantic 2 Space Textured Rackshelf 11.5IN. Deep Black Finish - RSH4S2S

Middle Atlantic RSH4S2S 2-Space Rack Shelf 11.5 Inch Deep Black

Overview

The Middle Atlantic RSH4S2S is a 2U (2-space) fixed rack shelf built for commercial AV, security, and IT enclosures where you need a solid horizontal surface to seat non-rack-mount gear — media converters, small receivers, unmanaged switches, or miscellaneous hardware that lacks its own rack ears. At 11.5 inches (292 mm) deep and 3.5 inches (89 mm) tall, it fits standard 19-inch rack rails and keeps equipment organized without fabricating custom brackets. The textured black steel finish blends with Middle Atlantic rack enclosures and most third-party open-frame and enclosed racks.

Key Features

• 2U (89 mm) height: occupies two rack spaces, giving enough vertical clearance to seat small-to-mid-size equipment that sits flat rather than sliding in on its own chassis. If your gear is thicker, measure before you commit — this is a fixed 2U shelf, not adjustable.
• 11.5-inch (292 mm) depth: accommodates most compact appliances and media gear without the shelf protruding past the front of a standard rack. Measure your deepest piece of equipment — gear deeper than 11.5 inches needs a different shelf model.
• Steel construction: handles the static load demands of typical rack-mounted components without flex or sag. Steel is the right call here over plastic alternatives when you need long-term dimensional stability in a permanently installed rack.
• Textured black finish: matches the standard Middle Atlantic enclosure palette and reduces glare inside open-frame racks under task lighting — a minor but practical detail in rack-dense control rooms.
• Greenguard certified: meets low-emission indoor air quality standards, relevant for deployments in occupied spaces such as school AV rooms, healthcare installations, or LEED-certified facilities where VOC compliance is required.
• RSH series compatibility: integrates into the RSH shelf family, making it straightforward to mix shelf depths and configurations within a single Middle Atlantic rack build.

Integration and Compatibility

The RSH4S2S mounts in any standard EIA 19-inch rack — open-frame, enclosed, or wall-mount. It is part of the Middle Atlantic RSH series, so it pairs directly with Middle Atlantic rack enclosures and rails. If you are building a full security or AV rack, consider pairing it with a rack enclosure and a power distribution unit for a complete infrastructure solution. Sold as a single unit (quantity per pack: 1).

Frequently Asked Questions

Q: What rack unit height does the RSH4S2S occupy?

A: The RSH4S2S is a 2U shelf, occupying two rack spaces (89 mm tall).

Q: How deep is the RSH4S2S shelf surface?

A: The shelf is 11.5 inches (292 mm) deep — suitable for compact appliances and media gear. Equipment deeper than 11.5 inches will overhang the shelf.

Q: Is the RSH4S2S Greenguard certified?

A: Yes, the RSH4S2S carries Greenguard certification, confirming it meets low-emission indoor air quality standards — relevant for healthcare, education, and LEED-compliant installations.

Q: What finish does the RSH4S2S come in?

A: It ships in a textured black steel finish, consistent with the standard Middle Atlantic enclosure color palette.

Q: Does the RSH4S2S fit standard 19-inch rack rails?

A: Yes, the RSH4S2S is designed for standard EIA 19-inch rack mounting and is part of the Middle Atlantic RSH series.

The RSH4S2S is a straightforward piece of infrastructure, but the 11.5-inch depth spec is the one that trips integrators up most often. I have seen racks where someone ordered a shallower shelf and ended up with equipment hanging over the front edge — a cable management and vibration problem waiting to happen. At 292 mm, this shelf gives you enough runway for most compact network gear and media converters without overhang, but it is still a fixed-depth shelf, so measure your deepest component before you spec it in.

Technical Highlights:

• 2U steel construction: 89 mm of vertical rack space in a steel chassis means no flex under the static load of a small appliance or receiver — aluminum shelves at this price point can bow over time under asymmetric loads.
• Greenguard certification: this matters if your rack lives in a classroom AV closet or a hospital comms room — Greenguard low-VOC compliance checks a real box on facility requirements documents without any extra cost or effort on your part.
• RSH series integration: designed to sit alongside other Middle Atlantic RSH-series components, so if you are building out a full rack with multiple shelf depths and panel blanks, everything mounts flush and at consistent depth.

Deployment Considerations:

• Confirm the rack rail spacing is standard EIA 19-inch before ordering — non-standard rack frames used in some older broadcast or custom millwork installations will not accept this shelf without modification.
• The 11.5-inch depth is the ceiling, not the floor — gear shallower than the shelf is fine, but there is no adjustable front stop, so lighter equipment should be secured or velcro-tied to prevent sliding during cable pulls.

The RSH4S2S is the right call for a security or AV control room rack where you need one or two surfaces for gear that does not rack-mount natively — specifically in Greenguard-sensitive environments like K-12 AV installs or healthcare communications closets where material certifications are reviewed during facility acceptance.
