Middle Atlantic 44SP Solid Split RD DRK - DCRD-44

Middle Atlantic DCRD-44 44U Solid Split Rear Door for DRK Series Racks

The Middle Atlantic DCRD-44 is a 44-rack-unit solid split rear door engineered specifically for the DRK base series — the right rear enclosure solution when you need clean airflow control, cable management discipline, and a finished look on the back of a full-height rack. At 78.32 inches tall and 27.11 inches wide, it covers a full 44U frame without shimming or custom fitment. If you've been searching for the DCRD-44 (often searched as DCRD 44), this is the factory-matched rear door for your DRK rack build.

Overview

Rear doors on equipment racks are often treated as afterthoughts — ordered late, fitted poorly, and swapped out when a cable run doesn't clear. The DCRD-44 eliminates that rework cycle by providing a split-panel solid door designed from the ground up for the DRK series. The split configuration means each panel swings independently, so you can access the right half of the rack for patching or drive swaps without fully clearing the aisle behind. Handles are included on both panels, giving technicians a positive grip during install and routine maintenance without reaching around the door edge.

Key Features

• 44 RU Coverage: At 78.32 in (198.9 cm) tall, the DCRD-44 covers a full 44U rack column — no exposed gap at the top or bottom where bypass air would short-circuit your hot/cold aisle containment scheme. Measure your DRK frame before ordering; this door is sized for the 44U variant specifically.
• Split-Panel Design: Two independently hinged panels let you open left or right independently. In a dense row where rear aisle clearance is tight, you can swing only the half you need rather than clearing the full door swing radius — a real advantage in under-floor access or wall-adjacent deployments.
• Solid Door Construction: Unlike vented or mesh rear doors, the solid panel fully encloses the rear of the rack. Pair this with a vented front door and a blanking panel strategy to force intake air through the front face and exhaust through top-mounted fans — solid rear doors are the correct choice for active rear-exhaust configurations where you want zero bypass.
• Integrated Handles: Factory-fitted handles on both panels mean no handle-kit add-on order. This keeps the fitment clean and avoids the common field problem of mismatched handle hardware rattling against door edges during vibration events (common in transport or seismic-zone installs).
• DRK Base Series Compatibility: The DCRD-44 is explicitly designed for the DRK series — not a universal fit door. If your rack frame is a different Middle Atlantic base series, verify the door series code before ordering. Using the correct series-matched door eliminates hinge alignment issues and ensures the latch geometry engages correctly.
• Compact Depth Footprint: At 2.87 in (7.3 cm) depth, the DCRD-44 adds less than 3 inches to the rear of the rack. In raised-floor data rooms where rear aisle width is governed by hot-aisle containment panels, every inch counts — this door won't push you outside your containment envelope.
• Manageable Shipping Weight: At 60 lbs (27.2 kg) shipping weight, the DCRD-44 ships as standard LTL freight. Two-person lift is recommended for installation given the 78-inch height, but the weight is within standard two-person handling limits for wall and aisle installs without mechanical assist.

Integration & Compatibility

The DCRD-44 is built for the Middle Atlantic DRK series rack ecosystem. If you're building out a full enclosure, pair this rear door with the matching front door and side panels from the same DRK accessory family to complete the enclosure. For rack enclosures running active cooling, consult your cooling and airflow planning guide before committing to solid versus vented rear doors — solid panels force airflow discipline but require that your exhaust path (top blanks, in-row coolers, or overhead return) is correctly sized for the rack's heat load. For cable egress through a solid rear door, Middle Atlantic offers brush-panel and grommet accessory kits separately; plan your cable exit strategy before the door goes on. If you're integrating this into a security rack system with video recorders, switches, or patch panels, the solid rear door also provides a clean finished appearance for client-facing equipment rooms.

Frequently Asked Questions

Q: What rack series is the DCRD-44 designed to fit?

A: The DCRD-44 is designed for the Middle Atlantic DRK base series racks. It is not a universal-fit rear door — verify your rack frame is a DRK series unit before ordering to ensure correct hinge alignment and latch engagement.

Q: What does the split design mean for installation?

A: The split design means the rear door consists of two independently hinged panels. Each panel swings open separately, so you can access one side of the rear of the rack without opening the full door — useful in tight rear aisles or wall-adjacent installations where full door swing isn't possible.

Q: Is the DCRD-44 a solid or vented rear door?

A: The DCRD-44 is a solid rear door. This makes it appropriate for active rear-exhaust airflow configurations where you want to eliminate bypass air. If your rack requires passive convective cooling through the rear, a vented rear door would be the correct choice instead.

Q: How much depth does the DCRD-44 add to the rear of the rack?

A: The DCRD-44 adds 2.87 inches (7.3 cm) to the rear of the rack. This is a relevant consideration when calculating rear aisle clearance, especially in hot-aisle containment designs with defined aisle widths.

Q: Does the DCRD-44 include handles?

A: Yes, handles are included on the DCRD-44. Both split panels come with factory-fitted handles — no separate handle kit required.

Q: What is the rack unit capacity of the DCRD-44?

A: The DCRD-44 covers 44 rack units (RU), measuring 78.32 inches (198.9 cm) in height. It is sized specifically for 44U DRK series rack frames.

The DCRD-44 is the rear door I spec when a client's DRK-series rack is going into an equipment room where airflow discipline actually matters. The 2.87-inch rear projection is the number I check first — in a hot-aisle containment row with 24-inch aisles, a door that adds 4+ inches pushes you out of containment geometry. The DCRD-44 stays under 3 inches, which keeps the rear blanking panel flush with the containment curtain rail in most standard APC and Eaton containment configurations.

Technical Highlights:

• 44 RU / 78.32 in height: Full-height coverage for a 44U DRK frame — no top or bottom gap that would allow hot exhaust recirculation back into the intake face of adjacent equipment.
• Split-panel configuration: Independent left/right swing means a single technician can service the right-rear cable tray without displacing the full door — reduces door-removal steps during moves, adds, and changes in live equipment rooms.
• Solid panel construction: Zero rear perforation means all exhaust airflow is directed through the designed exhaust path (top blanks, in-row cooler, or overhead return). Eliminates the rear bypass channel that vented doors introduce in passive-cooled racks.

Deployment Considerations:

• The DCRD-44 is a DRK-series-specific door — hinge points and latch geometry are matched to DRK frames. Do not attempt to fit it to WR, ERK, or other Middle Atlantic base series without confirming cross-series compatibility with the manufacturer, as hinge spacing varies by series.
• At 60 lbs shipping weight, plan for a two-person install. The 78.32-inch height makes single-person hinge alignment difficult and risks door drop if the hinge pin isn't fully seated before releasing.

The DCRD-44 is the correct spec for a DRK-based security operations rack — NVR rows, patch panels, managed switches — in any equipment room where the integrator is expected to deliver a clean, finished installation with documented airflow control. It is not the door for open-frame or partially enclosed builds where rear access frequency is high enough that a solid door becomes an operational obstacle.
