Middle Atlantic 44SP ERK Rear Door - ERK-RD-44

Middle Atlantic ERK-RD-44 44U ERK Series Solid Rear Door

The Middle Atlantic ERK-RD-44 is a solid rear door designed specifically for 44-rack-unit enclosures in the ERK series lineup. At 76.06 inches tall and 19.44 inches wide, it is dimensioned to close out the rear of a full-height ERK frame — delivering a finished, enclosed equipment bay without improvised panel work or aftermarket fitment guesswork. If you are already running Middle Atlantic rack infrastructure, this is the direct OEM replacement or add-on door for the 44U configuration.

Overview

Rear enclosure discipline matters in production AV, broadcast, security operations, and enterprise IT rooms where cable management, airflow containment, and physical access control all compete for priority. The ERK-RD-44 resolves the rear-access question for 44U ERK builds by providing a factory-matched panel that integrates without shimming, reworking mounting points, or sourcing third-party alternatives. For integrators specifying rack enclosure systems across multi-rack deployments, using the manufacturer-matched door eliminates the fit and finish risk that shows up during final inspection. The door ships at 32.88 lbs (14.9 kg), so plan for a two-person install when working overhead or in tight MDF/IDF closets.

Key Features

• 44 RU Capacity Match: Engineered to close out a full 44U ERK rack bay — spanning 76.06 inches of vertical height. Mismatched doors on deep enclosures leave gaps at top or bottom that compromise cable containment and defeat any hot/cold aisle separation strategy you have in place.
• ERK Series Integration: The ERK-RD-44 (often searched as ERK RD 44) is built to the ERK base series specification. That means mounting geometry, hinge alignment, and panel depth are validated against the ERK frame — no field modification required to achieve a flush fit.
• Panel Depth of 1.22 Inches: At just over an inch of depth, this door adds minimal protrusion to the rear of the rack footprint. In raised-floor environments or tight-clearance server rooms where rear access paths are constrained, that 1.22-inch profile keeps your aisle clearance compliant and your facilities team satisfied.
• 19.44-Inch Panel Width: Standard 19-inch rack width with the 19.44-inch overall dimension accounts for the mounting ears and frame — consistent with EIA-310 rack standards. No custom cutouts, no adapter plates.
• Shipping Weight of 32.88 lbs: The door arrives as a single panel at approximately 33 lbs. Factor this into your logistics staging — particularly if the installation floor is above grade and elevator access is limited. A two-person lift is the correct call for overhead mounting scenarios.
• Solid Panel Construction: A solid rear door provides the physical access barrier needed when racks are deployed in shared spaces, co-location environments, or security operations centers where rear-cable access should be controlled and not open to casual contact.

Integration and Compatibility

The ERK-RD-44 is matched to Middle Atlantic's ERK rack series. If your enclosure is a different Middle Atlantic series — such as the BGR or WMRK line — verify the series designation before ordering, as door geometry is not interchangeable across frame families. This door is intended for rack enclosure accessories sourced to the ERK build spec. Integrators specifying mixed-series rack rooms should pull the rack frame model number and confirm the ERK base series designation before requisitioning this SKU.

For system integrators building out security operations centers, broadcast equipment rooms, or enterprise IT closets on Middle Atlantic rack infrastructure, pairing the correct rear door with your 44U ERK frame is a finish-quality detail that matters during client walkthroughs and annual maintenance visits alike. Consider also reviewing rack power distribution units and cable management accessories that pair with ERK-series enclosures to complete the rear bay build-out.

Frequently Asked Questions

Q: Which rack series is the ERK-RD-44 designed to fit?

A: The ERK-RD-44 is designed for Middle Atlantic's ERK base series rack enclosures. It is not confirmed to be interchangeable with other Middle Atlantic series (BGR, WMRK, etc.) — verify your frame's base series before ordering.

Q: What is the rack unit height of the ERK-RD-44?

A: The ERK-RD-44 covers 44 rack units, with an overall panel height of 76.06 inches (193.2 cm).

Q: How much does the ERK-RD-44 weigh for shipping purposes?

A: The shipping weight is 32.88 lbs (14.9 kg). Plan for a two-person install, particularly in overhead or tight-clearance environments.

Q: What are the overall panel dimensions of the ERK-RD-44?

A: Height: 76.06 in (193.2 cm), Width: 19.44 in (49.4 cm), Depth: 1.22 in (3.1 cm).

Q: Can the ERK-RD-44 be used for hot/cold aisle containment?

A: A solid rear door like the ERK-RD-44 contributes to rear-of-rack closure, which supports aisle containment strategies. Full containment effectiveness depends on the complete rack build and room configuration — the door alone is one component of that system.

I spec ERK-series doors regularly for security operations center builds and enterprise IT closets, and the ERK-RD-44 comes up whenever a 44U frame needs a rear closure that installs cleanly without field modification. The 1.22-inch panel depth is what I pay attention to first — in rooms where rear aisle clearance is tight, that number determines whether your facilities team signs off on the layout.

Technical Highlights:

• 76.06-Inch Panel Height: Covers the full 44U vertical run of an ERK frame — no gap panels, no filler strips needed at top or bottom of the bay.
• 19.44-Inch Panel Width: Matches EIA-310 rack standards; mounts flush to ERK frame geometry without shimming or adapter hardware.
• 32.88 lb Shipping Weight: Heavier than it looks for a single panel — two-person install is the right call, especially above 6 feet in confined MDF/IDF spaces.

Deployment Considerations:

• Confirm your rack frame carries the ERK base series designation before ordering — Middle Atlantic produces multiple frame families and door geometry is series-specific, not universal.
• The 1.22-inch panel depth adds to your total rack footprint at the rear; measure your rear aisle clearance before finalizing rack placement, particularly in raised-floor rooms with fixed tile grids.

The ERK-RD-44 is the right call for 44U ERK builds in security operations centers and enterprise equipment rooms where rear cable access needs to be controlled and the installation needs to pass a professional finish inspection — not a general-purpose door for any rack in the room.
