Middle Atlantic Large Perforated Vented Rear Door 44 Space WRK MRK VRK Racks Black - MW-LVRD-44

Middle Atlantic MW-LVRD-44 44U Large Perforated Vented Rear Door

The Middle Atlantic MW-LVRD-44 is a 44-rack-unit large perforated vented rear door designed to retrofit onto WRK, MRK, and VRK series racks from Middle Atlantic. At 78.1 inches tall and 19.29 inches wide, it spans the full height of a 44U enclosure — giving you a single-piece vented rear panel that replaces a solid door or fills an open rear on qualifying Middle Atlantic rack systems. If you're building out a security head-end, network closet, or AV equipment room where rear access and airflow both matter, this door addresses both without requiring a new rack purchase.

Key Features

• 44U Full-Height Coverage: At 78.1 in (198.4 cm) tall, the MW-LVRD-44 covers the entire rear face of a 44-space enclosure — no partial gaps, no patchwork panels. One door, one installation, done.
• Perforated Vented Design: The large perforation pattern allows passive rear airflow, which matters in high-density deployments where heat buildup shortens equipment life. Vented rear access is a standard requirement in any rack housing NVRs, switches, or patch panels running continuously.
• Narrow Profile — 1.37 in Depth: At just 1.37 inches (3.5 cm) deep, the door adds minimal footprint behind the rack. In tight equipment rooms or server closets where rear clearance is limited, that shallow profile keeps you within standard aisle spacing requirements.
• 19.29 in Width: The 19.29-inch width is matched to standard 19-inch rack geometry, aligning with the WRK, MRK, and VRK base series without modification or shimming.
• Black Finish: The black finish is consistent with Middle Atlantic's rack line aesthetics — relevant if you're matching existing enclosures in a finished equipment room or broadcast-style head-end where visual uniformity is expected.
• Shipping Weight 33 lbs: At 33 lbs (15 kg) shipped, this is a substantial steel component. Plan for two-person installation if you're working at height or in a tight space — the door's 78-inch span makes solo handling awkward.

Integration and Compatibility

The MW-LVRD-44 is verified compatible with Middle Atlantic WRK, MRK, and VRK series rack enclosures in the 44U configuration. If you are specifying a new rack build or replacing a damaged or solid rear door on an existing enclosure, confirm your base rack is one of these three series before ordering. Middle Atlantic's rack line includes several series with similar form factors but different door mounting geometries — compatibility is series-specific, not universal across the entire catalog. For guidance on pairing rack doors with the right enclosure, consult a rack accessories resource or the base rack's installation documentation.

This door works within standard network rack cabinet deployments where rear ventilation is required by facility or equipment specs. It is not a locking door — if physical security of the rear panel is a requirement, verify whether a locking variant exists in the Middle Atlantic LVRD line.

Frequently Asked Questions

Q: Which rack series is the MW-LVRD-44 compatible with?

A: The MW-LVRD-44 is compatible with Middle Atlantic WRK, MRK, and VRK series racks in the 44U (44-space) configuration. It is not a universal fit — verify your base rack series before ordering.

Q: What are the physical dimensions of the MW-LVRD-44?

A: The door measures 78.1 inches (198.4 cm) tall, 19.29 inches (49 cm) wide, and 1.37 inches (3.5 cm) deep. Shipping weight is 33 lbs (15 kg).

Q: Does the MW-LVRD-44 include a lock?

A: Based on available product specifications, no locking mechanism is documented for the MW-LVRD-44. If rear-door physical security is required, verify with Middle Atlantic whether a locking variant is available in the LVRD series.

Q: Can the MW-LVRD-44 be used on racks other than WRK, MRK, and VRK?

A: The verified compatible base series are WRK, MRK, and VRK. Compatibility with other Middle Atlantic rack series or third-party enclosures is not confirmed in the product specifications — do not assume fit based on rack unit count alone.

Q: Is the MW-LVRD-44 the same as MW LVRD 44?

A: Yes — MW-LVRD-44 (sometimes searched as MW LVRD 44) is the same part. The hyphenated form is the manufacturer's official model number.

The MW-LVRD-44 is the right call when you're closing out the rear of a 44U WRK, MRK, or VRK rack and need airflow, not a solid panel. At 78.1 inches tall and just 1.37 inches deep, it fits flush against the rack without eating into rear aisle clearance — a real consideration in head-end rooms where you're working with 24 to 36 inches of service space behind the cabinet.

Technical Highlights:

• 44U Full-Height Fit: 78.1 in / 198.4 cm covers the complete rear face of a 44-space enclosure — no partial coverage, no stacking two shorter doors.
• 1.37 in Depth: Minimal rear projection means you stay within standard rear-aisle clearance specs even in tight equipment rooms.
• Series-Specific Compatibility: Verified for WRK, MRK, and VRK only — not a cross-series or third-party fit. Confirm base rack series before specifying.

Deployment Considerations:

• At 33 lbs shipped (15 kg), plan for two-person handling during installation — the 78-inch span is unwieldy solo, especially if you're working at the top of a rack on a raised floor or in a low-ceiling IDF closet.
• No locking mechanism is documented for this door. If you need rear-panel physical security as part of your deployment spec — common in co-location or multi-tenant environments — verify whether a locking LVRD variant exists before committing to this SKU.

This door fits naturally into a security head-end or AV integration rack build where a 44U WRK or MRK enclosure is already specified and you need to close the rear with ventilation rather than a solid panel. It is not the right choice for open-frame racks, non-Middle Atlantic enclosures, or deployments where rear-door locking is a hard requirement.
