Middle Atlantic Fully Vented Rear Door Option for 44 Space DRK Series Racks Steel Black - DFVRD-44

Middle Atlantic DFVRD-44 Fully Vented Rear Door for 44U DRK Series Racks

Overview

The Middle Atlantic DFVRD-44 is a 100% open-area vented rear door designed specifically for 44-space DRK series rack enclosures. At 78.1 inches tall and 27.29 inches wide with a 1.5-inch depth profile, this steel door — finished in black powder coat — replaces a solid rear panel with unobstructed airflow across the full rear face of the rack. For AV, security, and IT integrators who need maximum passive convection in equipment-dense deployments, 100% vent open area means zero restriction on the exhaust path: hot air rising from densely populated 44U enclosures exits freely rather than recirculating. The DFVRD-44 (often searched as DFVRD 44) is engineered as a direct-fit option for the DRK series, not a universal retrofit, so dimensional alignment is guaranteed within the Middle Atlantic ecosystem.

Key Features

• 100% Vent Open Area: Unlike perforated doors that typically offer 60–70% open area, the DFVRD-44 provides completely unobstructed airflow across the entire rear panel. In a fully loaded 44U rack running NVRs, servers, or dense power distribution, this eliminates the rear door as a thermal bottleneck — critical when ambient temperature margins are tight.
• 44U / 78.1-Inch Height: Matched exactly to 44-space DRK series enclosures. At 78.1 inches (198.4 cm), this door spans the full rack height without panel gaps that would allow bypass airflow to short-circuit around equipment rather than through it.
• 27.29-Inch Width: Fits the DRK series rack footprint at 27.29 inches (69.3 cm) wide — verify your DRK enclosure model before ordering, as Middle Atlantic offers multiple rack widths across the series.
• 1.5-Inch Depth Profile: The door adds only 1.5 inches (3.8 cm) to the rear depth of the enclosure. In tight IDF closets or equipment rooms where rear clearance is constrained, this slim profile preserves usable aisle space while still delivering full ventilation.
• Steel Construction, Black Powder Coat Finish: Commercial-grade steel construction provides the rigidity to stay dimensionally stable over years of repeated access without warping or binding. The black powder coat finish matches standard DRK rack aesthetics and resists corrosion in typical indoor equipment room environments.
• DRK Series Direct-Fit: The DFVRD-44 is purpose-built for the DRK base series — not a cut-to-fit panel or a universal door. Direct-fit integration means consistent hinge alignment, latch engagement, and panel seating without field modification.

Integration and Compatibility

The DFVRD-44 is compatible with 44-space Middle Atlantic DRK series rack enclosures. The DRK series is a widely deployed open-frame and enclosed rack line used in security operations centers, network equipment rooms, AV production environments, and broadcast facilities. If your installation uses a DRK enclosure with a different rack unit count (e.g., 26U, 36U), a different DFVRD model is required — the door height is fixed at 44U and will not fit shorter or taller enclosures. For rack enclosures and related Middle Atlantic rack accessories, confirm your DRK series model number before specifying this door. Integrators deploying high-density NVR stacks or network video recorders in enclosed cabinets will find the 100% open rear particularly valuable — NVR appliances running continuous 24/7 recording workloads generate sustained heat that perforated or solid rear doors can trap. Pair with a front vented door or active fan panel if the enclosure requires positive-pressure airflow management. For guidance on thermal planning in equipment enclosures, consult a rack cooling solution alongside this door option.

Frequently Asked Questions

Q: What rack series is the DFVRD-44 compatible with?

A: The DFVRD-44 is designed for Middle Atlantic DRK series rack enclosures with 44 rack spaces (44U). It is not a universal door and will not fit non-DRK enclosures or DRK enclosures of different rack unit counts.

Q: What is the vent open area percentage on the DFVRD-44?

A: 100%. The DFVRD-44 provides completely unobstructed airflow across the full rear panel — there is no solid material blocking the exhaust path, unlike perforated doors that typically achieve 60–70% open area.

Q: What are the physical dimensions of the DFVRD-44?

A: The door measures 78.1 inches (198.4 cm) tall, 27.29 inches (69.3 cm) wide, and 1.5 inches (3.8 cm) deep. Shipping weight is 56 lbs (25.4 kg).

Q: Is the DFVRD-44 a drop-in replacement for the stock DRK rear door?

A: Yes — the DFVRD-44 is engineered as a direct-fit option for the 44-space DRK series, so hinge points and latch geometry align with the existing enclosure without field modification.

Q: What finish does the DFVRD-44 have?

A: Steel construction with a black powder coat finish, matching standard DRK series rack aesthetics.

The spec that matters most on the DFVRD-44 is the one that sounds obvious until you've cooked a rack: 100% vent open area. Most vented doors in this category run 60–70% perforation — that remaining 30–40% solid material is a real restriction when you're exhausting heat from a fully loaded 44U enclosure running NVRs or dense switching gear around the clock. The DFVRD-44 removes that restriction entirely.

Technical Highlights:

• 100% Open Vent Area: No perforation pattern, no material obstruction — the full rear face of the 44U enclosure is open exhaust path. In continuous-duty security and AV deployments, this is the difference between a door that helps thermal management and one that merely looks vented.
• 1.5-Inch Depth Addition: Adds only 3.8 cm to enclosure rear depth. In IDF closets or SOC equipment rows where rear-of-rack clearance is measured in inches, that slim profile matters. You keep full airflow without sacrificing aisle width.
• Direct-Fit DRK Series Integration: At 78.1 inches tall and 27.29 inches wide, this door is dimensioned to the 44-space DRK footprint — no shimming, no cutting, no field adaptation. Hinge and latch geometry aligns out of the box.

Deployment Considerations:

• This door is 44U-specific. If your DRK enclosure is a different rack unit count, the DFVRD-44 will not fit — confirm your enclosure model against the DRK series lineup before ordering. Middle Atlantic offers DFVRD variants for other RU counts.
• 100% open area means no physical access restriction from the rear. In shared equipment rooms or co-location environments where rear physical security matters, pair this with an active monitoring approach or a keyed enclosure at the front — the vented rear provides zero intrusion resistance on its own.

The DFVRD-44 is the right specification for high-density security or AV equipment rooms where 44U DRK enclosures are running continuous workloads — NVR stacks, dense PoE switching tiers, or broadcast-grade processing — and where thermal management has already surfaced as a problem with the stock door.
