Middle Atlantic DRK LRG Perf Vent Reardr - DLVRD-44

Middle Atlantic DLVRD-44 44RU Vented Rear Door

The Middle Atlantic DLVRD-44 is a vented rear door engineered specifically for 44RU DRK series open-frame and enclosed rack systems. Measuring 78.1 in tall, 27.29 in wide, and just 1.5 in deep, it closes out the rear of a full-height DRK rack while preserving passive airflow through its vented panel construction. For integrators building out equipment racks in security operations centers, AV control rooms, or IT closets, this door is a direct-fit accessory that finishes the enclosure without requiring modification.

Key Features

• 44RU capacity: Spans the full height of a 44RU DRK rack at 78.1 in (198.4 cm), eliminating the need to mix-match partial doors.
• Vented panel: Perforated construction allows passive convection airflow from front to rear, reducing heat buildup in densely populated racks.
• Slim 1.5 in depth: At only 1.5 in (3.8 cm), the door adds minimal rear footprint, keeping the rack within tight wall-clearance tolerances.
• 27.29 in width: Matches the DRK series rack width exactly, providing a flush, finished appearance on both sides.
• 55 lb shipping weight: Substantial steel construction at a shipping weight of 55 lbs (25 kg) indicates a rigid, warp-resistant panel suitable for permanent installations.
• DRK series compatibility: Drop-in fit with Middle Atlantic DRK racks means no drilling, adapter plates, or field modifications at install time.
• Rear enclosure without blocking service access: A removable rear door keeps cabling and equipment accessible for moves, adds, and changes after installation is complete.

Integration & Compatibility

The DLVRD-44 is purpose-built for the Middle Atlantic DRK series rack line. Before ordering, confirm your DRK rack is the 44RU variant — Middle Atlantic produces the DRK in multiple rack unit heights, and the door must match the RU count of the base frame. The 27.29 in width aligns with standard DRK rack dimensions; if you are working with a non-standard or modified frame, measure the rear door opening before ordering.

For integrators managing full rack deployments, pairing this door with matching rack accessories such as side panels, blanking panels, and cable management keeps the finished installation clean and consistent. Rear vented doors like this one are typically used in conjunction with front-mount active cooling or natural convection layouts — review your thermal plan for the rack before deciding between a solid and vented door variant. Browse our full selection of Middle Atlantic racks and rack doors to compare door options across the DRK and other rack families.

Installation requires standard hand tools. The door hinges to the DRK frame using Middle Atlantic's standard rear-door hardware; verify that the DRK rack you are working with includes or supports the corresponding hinge mounting points. For structured cabling environments, consider coordinating door placement with cable management runs before final installation.

Frequently Asked Questions

Q: Is the DLVRD-44 compatible with all Middle Atlantic rack series, or only the DRK?

A: The DLVRD-44 is designed specifically for the DRK series. Middle Atlantic doors are rack-family-specific due to hinge mount geometry and frame width tolerances. Do not assume cross-series compatibility without verifying the part number against your specific rack model.

Q: Does the vented design significantly reduce airflow restriction compared to a solid rear door?

A: Vented rear doors allow passive convective airflow through the perforations, which reduces heat accumulation in racks with moderate equipment density. For high-density or high-wattage loads, active cooling solutions should still be evaluated in addition to the vented door.

Q: What is the actual installed depth added by this door?

A: The DLVRD-44 adds 1.5 in (3.8 cm) to the rear of the rack when closed. Account for this when planning wall clearance or back-to-back rack layouts in tight rooms.

Q: Is hardware included for mounting the door to the DRK rack?

A: Mounting hardware inclusion is not confirmed in available product data. Contact Middle Atlantic or your distributor to confirm whether hinge hardware ships with the door or is sold separately for your specific DRK rack configuration.

Q: Can this door be used on a 44RU rack from a different manufacturer?

A: This door is engineered to fit Middle Atlantic DRK series racks. Fitting it to a third-party rack would require verifying that the rear opening dimensions and hinge mounting points match exactly, which is not a supported or documented configuration.

The DLVRD-44 is the kind of accessory that gets overlooked at the BOM stage and then becomes urgent on install day. At 78.1 in tall and 27.29 in wide, this door closes out a full 44RU DRK rack precisely — there is no trimming, shimming, or field adaptation involved when you have the right rack underneath it.

Technical Highlights:

• Full 44RU height coverage: 78.1 in (198.4 cm) matches the DRK 44RU frame exactly, eliminating partial-door stacking or gap panels at the rear.
• Minimal rear depth penalty: 1.5 in added depth at the rear keeps the overall rack footprint predictable in rooms where back-wall clearance is constrained to 6 in or less.
• Shipping weight as a build-quality indicator: At 55 lbs (25 kg) shipped, the panel carries enough steel mass to resist racking or warping under normal handling — relevant in installations where the door will be opened and closed frequently during MACs.

Deployment Considerations:

• Confirm the base DRK rack is the 44RU variant before ordering — Middle Atlantic's DRK line spans multiple RU heights and the door-to-frame fit is not interchangeable across sizes.
• The vented construction supports passive airflow but does not substitute for active cooling in racks with sustained high-wattage loads; treat it as a complement to a thermal plan, not a replacement for one.

For a security operations center or AV control room rack that needs a finished rear enclosure with basic airflow management, the DLVRD-44 is a straightforward, purpose-matched fit for the DRK 44RU platform — no engineering workarounds required.
