Middle Atlantic 24SP Large Perf FR Door - LVFD-24

Middle Atlantic LVFD-24 24RU Large Vented Front Door

Overview

The Middle Atlantic LVFD-24 is a 24-rack-unit vented front door engineered for the DWR enclosure series, delivering 64% open-area ventilation in a textured black powder-coat finish. If you're running active equipment — switches, media converters, power strips, or dense patch environments — inside a fully enclosed rack, thermal management is non-negotiable. The LVFD-24 answers that requirement without forcing a compromise between airflow and physical access control.

At 42.87 inches tall and 20.04 inches wide, the LVFD-24 spans the full face of a standard 24RU enclosure opening, replacing a solid panel with a large-format perforated surface that passes nearly two-thirds of its face area as open airflow. That's a meaningful difference from economy perf doors that typically land in the 40–50% range. For integrators spec'ing rack enclosures in IDF closets or equipment rooms where active cooling is limited, this door can be the difference between running within thermal limits and triggering hardware throttling.

Key Features

• 64% Vent Open Area: Nearly two-thirds of the door face passes air — substantially more than entry-level perforated doors. In a sealed telecom closet with no forced-air cooling, this passive ventilation can drop internal rack temps enough to keep switches and media converters within spec without adding a dedicated fan panel.
• 24RU Panel Span: Sized precisely for 24-rack-unit enclosures — no shimming, no adapters. The door fits the DWR base series footprint exactly, so installation is a direct mount rather than a fitment project.
• 42.87 in × 20.04 in Exterior Envelope: Full-face coverage at 108.9 cm tall and 50.9 cm wide. The dimensional precision matters when you're replacing a factory door mid-deployment — measure once against the LVFD-24 spec and you're done.
• 1.39 in Profile Depth: At 3.5 cm deep, the door adds minimal projection beyond the rack frame. Tight equipment rooms and wall-adjacent installs won't require clearance rework to accommodate it.
• Textured Black Powder Coat Finish: The matte black texture resists fingerprints and minor scuffs better than gloss finishes — relevant in high-traffic equipment rooms where doors get handled regularly by multiple technicians. It also matches the standard DWR enclosure aesthetic without needing a paint match.
• DWR Base Series Compatibility: Designed as a factory-fit replacement or upgrade door for Middle Atlantic DWR enclosures. No third-party adaptation brackets required.
• WRK and MRK Series Fit (SR): Beyond the DWR base, the LVFD-24 is confirmed compatible with WRK and MRK rack series — broadening deployment options across Middle Atlantic's enclosure lineup without requiring a separate SKU for each frame type.

Integration & Compatibility

The LVFD-24 (often searched as LVFD 24) is engineered for Middle Atlantic's DWR enclosure series, with documented fit across WRK and MRK series racks as well. If your project uses a mix of enclosure types from the Middle Atlantic lineup, this door covers the widest base without SKU proliferation. For AV integration environments running rack-heavy system designs, pairing the LVFD-24 with a rear vented door on the same enclosure creates a full front-to-back airflow path — the perforated front draws passive intake while a rear exit point exhausts heat. For deeper deployments within rack accessories ecosystems, confirm the specific DWR model's door mounting rail spacing against Middle Atlantic's dimensional documentation before ordering a multi-unit deployment.

This door is a passive ventilation component — it has no power requirements, no cabling, and no firmware. Installation is mechanical: the door mounts to the existing hinge points on compatible enclosures. Lead time from order to rack is dictated by shipping, not configuration.

Frequently Asked Questions

Q: What rack series is the LVFD-24 compatible with?

A: The LVFD-24 is designed for Middle Atlantic DWR enclosures and is also confirmed compatible with WRK and MRK series racks per the manufacturer's specifications.

Q: What is the vent open area percentage on the LVFD-24?

A: The LVFD-24 provides 64% vent open area across its perforated face — meaning nearly two-thirds of the door surface is open to airflow.

Q: What are the exact dimensions of the LVFD-24?

A: The LVFD-24 measures 42.87 in (108.9 cm) tall, 20.04 in (50.9 cm) wide, and 1.39 in (3.5 cm) deep. It is sized for a 24RU rack opening.

Q: What finish does the LVFD-24 have?

A: The door ships in a textured black powder coat finish, matching the standard Middle Atlantic DWR enclosure aesthetic.

Q: Does the LVFD-24 require any additional hardware or adapters to install on a compatible rack?

A: No. The LVFD-24 is a factory-fit door for compatible Middle Atlantic enclosures and does not require additional adapters when installed on DWR, WRK, or MRK series racks.

Q: What is the shipping weight of the LVFD-24?

A: The LVFD-24 ships at 17 lbs (7.7 kg).

Eden Phillips

The spec that drives most of my recommendations on the LVFD-24 is the 64% vent open area — that's not a marketing number, that's a geometric fact about how much of the 42.87-inch face is actually open versus solid steel. When I'm spec'ing this door for a DWR enclosure loaded with PoE switches and NVRs, that 64% figure is what separates passive thermal management that actually works from a door that just looks perforated.

Technical Highlights:

• 64% Open Area: At nearly two-thirds open face, this door enables genuine passive convective airflow through the rack — relevant in any closet installation where you can't guarantee forced-air cooling from HVAC.
• 1.39 in Profile: The shallow 3.5 cm depth means you're not eating into front clearance. In tight wall-mount or shallow-alcove installations, this matters — you won't need to reposition the rack to accommodate the door swing envelope.
• Multi-Series Fit (WRK/MRK/DWR): One SKU covers three Middle Atlantic rack series, which simplifies procurement on larger projects running mixed enclosure types across a facility.

Deployment Considerations:

• The LVFD-24 is a passive-only solution — it moves air by convection and won't compensate for a sealed rack in a high-ambient-temperature room. If your IDF closet runs above 80°F ambient, pair this with an active fan panel rather than relying on the door alone.
• At 17 lbs shipping weight, the door itself is substantial — budget handling time during installation, particularly in overhead or elevated rack positions where single-person door mounting is awkward.

For a network security or surveillance equipment room running a DWR enclosure with 15–20 RU of active PoE gear and no dedicated precision cooling, the LVFD-24 is the straightforward thermal mitigation upgrade — factory fit, no configuration, immediate airflow improvement on an existing enclosure.
