Middle Atlantic 4SP Textured RSH Face ONL - SFACE4

Middle Atlantic SFACE4 4U Textured Rack Face Plate for RSH Series Enclosures

Overview

The Middle Atlantic SFACE4 is a 4U blank face plate designed exclusively for the Middle Atlantic RSH Series rack enclosure line. Machined from aluminum at 482.6 mm wide × 177.8 mm tall × 12.9 mm deep, it closes off unused rack space in a standard 19-inch bay — preventing dust ingress, maintaining airflow management, and giving your rack a finished, professional appearance. If you're populating a rack enclosure and have open 4U gaps, the SFACE4 is the correct blank to specify.

The textured black finish matches the standard Middle Atlantic RSH aesthetic, so mixed-population racks — where some 4U slots are blanked and others hold active equipment — look consistent rather than cobbled together. GreenGuard certification means the panel meets indoor air quality standards, relevant for deployments in occupied spaces like network operations centers, control rooms, and data closets where VOC emissions from rack hardware are a legitimate consideration.

Key Features

• 4U / 19-inch standard form factor (482.6 mm × 177.8 mm): fits any EIA-standard 19-inch rack, but the SFACE4 is specifically engineered for the RSH Series — mounting hole pattern and panel depth (12.9 mm) align with RSH hardware tolerances, avoiding the rattle and misalignment common with generic blanks.
• Aluminum construction: aluminum is dimensionally stable and won't warp under the thermal cycling that happens in active equipment racks. A warped blank is a gap — defeating the entire purpose of filling the slot. Aluminum also contributes meaningfully less weight than steel equivalents, useful when rack weight budgets are tight.
• Textured black finish: matches the RSH Series panel aesthetic. In environments where racks are customer-visible — executive briefing centers, security operations centers, customer-facing server rooms — visual consistency matters. Mismatched finishes signal careless installation.
• GreenGuard certified: the panel meets UL's GreenGuard indoor air quality standard for chemical emissions. This is a legitimate differentiator for installations in occupied, ventilated spaces (NOCs, dispatch centers, control rooms) where equipment certifications are reviewed during facility approvals or LEED compliance audits.
• RSH Series compatibility: specified and engineered for the Middle Atlantic RSH enclosure family. Using the manufacturer-matched blank eliminates the guesswork of whether a third-party panel will seat flush, align with the rack's screw pattern, or gap at the edges.
• Single unit pack quantity: sold individually, so you can order the exact count needed for your rack layout without carrying surplus inventory. Useful for service technicians doing partial builds or add-ons to existing racks.

Integration & Compatibility

The SFACE4 is designed for the Middle Atlantic RSH Series rack enclosure line. The 482.6 mm (19-inch) width and 177.8 mm (4U) height conform to EIA-310 rack unit standards, but compatibility is specifically validated for RSH Series hardware. Before ordering for other Middle Atlantic enclosure families, verify the mounting pattern matches your specific enclosure model. This panel does not include integrated cable management, ventilation, or power — it is a blank closure panel only. For installations requiring active rack management solutions such as vented blanks, brush panels, or cable troughs, those are separate SKUs in the Middle Atlantic line.

The HS code 85389099 classifies this panel as an electrical apparatus part — relevant for procurement teams managing import documentation or harmonized tariff compliance on international projects.

Frequently Asked Questions

Q: Is the SFACE4 compatible with rack enclosures other than the Middle Atlantic RSH Series?

A: The SFACE4 is engineered specifically for the Middle Atlantic RSH Series enclosure line. The 482.6 mm width conforms to standard 19-inch EIA-310 rack dimensions, so physical fit in other 19-inch racks is likely, but mounting hole alignment and panel depth (12.9 mm) are validated for RSH Series hardware. Compatibility with other Middle Atlantic enclosure families or third-party racks should be verified against those enclosures' mounting specifications before ordering.

Q: What is the rack unit height of the SFACE4?

A: The SFACE4 occupies 4U (four rack units) of vertical space. At 177.8 mm tall and 482.6 mm wide, it fills a standard 4U slot in an EIA-310 19-inch rack.

Q: What material and finish does the SFACE4 use?

A: The panel is constructed from aluminum with a textured black finish. The finish matches the standard Middle Atlantic RSH Series aesthetic for visual consistency in mixed-population racks.

Q: What does GreenGuard certification mean for the SFACE4?

A: GreenGuard certification indicates the SFACE4 meets UL's indoor air quality standard for chemical emissions. This is relevant for installations in occupied spaces — such as network operations centers, control rooms, or dispatch centers — where equipment VOC emissions may be reviewed for facility compliance or LEED certification purposes.

Q: How many panels are included per order?

A: The SFACE4 is sold as a single unit (quantity per pack: 1). Order the exact quantity needed for your rack layout.

Q: Does the SFACE4 include ventilation or cable management features?

A: No. The SFACE4 is a solid blank closure panel with no ventilation slots, brush strips, or cable pass-throughs. If you need vented blanks or cable management panels for airflow control, those are separate Middle Atlantic SKUs.

James Everett

The SFACE4 is one of those components that gets overlooked in a rack BOM until you're on-site with open slots and no blanks. At 12.9 mm deep, this panel sits flush within the RSH Series enclosure profile — not proud of the rack face, not recessed — which matters when your enclosure has a door and panel clearance is tight. It's a simple part, but specifying the correct OEM blank for the RSH Series saves the rework of swapping a loose-fitting generic later.

Technical Highlights:

• Aluminum at 177.8 mm × 482.6 mm × 12.9 mm: the 12.9 mm depth is matched to RSH Series door clearance tolerances — an important detail in enclosed rack deployments where panel depth variation causes door interference.
• GreenGuard certification: documented chemical emission compliance for the panel material, not just a marketing label — this is a UL-verified standard that can be cited in facility documentation for occupied NOCs or control rooms undergoing indoor air quality review.
• Single-unit pack quantity: sold individually, which lets you fill only the open slots your layout actually has rather than buying in multiples and carrying leftover panels across job sites.

Deployment Considerations:

• Confirm you are installing into an RSH Series enclosure before ordering. The mounting hole pattern on the SFACE4 is validated for RSH hardware — using it in a different Middle Atlantic enclosure family may require checking that the hole spacing matches.
• The SFACE4 is a solid blank — no perforation, no brush strips, no ventilation. If your rack thermals require airflow through unused slots, you need a vented blank panel instead. Blanking a hot rack with a solid panel without considering airflow path can concentrate heat at equipment above or below the blank.

The SFACE4 is the right spec for finishing out an RSH Series rack in a permanently installed environment — security operations center buildouts, on-premise NVR/server closets, and control room infrastructure where the enclosure will be sealed, presented to clients, or inspected during commissioning. Don't leave open slots in a commissioned rack.
