Middle Atlantic Vented Front Door Fits 24 Space DWR MRK WRK Series Racks Black Textured - VFD-24

Middle Atlantic VFD-24 Vented Front Door for 24U DWR, WRK, and MRK Series Racks

Overview

The Middle Atlantic VFD-24 is a replacement vented front door engineered specifically for 24-rack-unit enclosures in the DWR, WRK, and MRK series. At 42.87 inches tall and 20.04 inches wide, it drops into place on those rack frames without modification — no cutting, no adapter plates, no guesswork on fitment. The textured black powder coat finish matches the factory finish on Middle Atlantic racks so the install looks intentional rather than pieced together. If you're managing equipment heat in a server closet, AV rack room, or security operations head-end, this door gives you a defined, controlled airflow path without pulling the rack out of service.

Key Features

• 25% Vent Open Area: A quarter of the door face is open to airflow — enough to let convection and active fans pull heat away from densely populated NVR and networking gear without the door becoming the bottleneck. If your rack runs hot gear (high-wattage switches, recorders, UPS units), this matters more than the door aesthetics.
• Precision Fit for 24U Enclosures: Designed to fit the DWR, WRK, and MRK series racks specifically. The 42.87 in (108.9 cm) height and 20.04 in (50.9 cm) width are frame-matched — you're not shimming or forcing this into place. Compatibility is limited to these series, so confirm your rack model before ordering.
• Textured Black Powder Coat Finish: Powder coat is more durable than painted finishes under repeated handling — doors get opened and closed constantly in active equipment rooms. The textured surface also hides minor scuffs that would show on a gloss finish, which matters in high-traffic installations.
• Shallow Profile (1.39 in Depth): At just 1.39 inches (3.5 cm) of added depth, this door doesn't meaningfully change your rack footprint. Useful when clearance is tight in front — server rooms and structured wiring closets often have exactly 24–36 inches of front-access clearance, and a bulky door eats into that fast.
• Lightweight Construction (19.85 lbs Shipping Weight): A door in this size class that ships at under 20 lbs is handling-friendly for a one-person install. You're not wrestling a heavy steel panel while also trying to align hinge points on a fully loaded rack.
• Series Compatibility — DWR, WRK, and MRK: Three separate rack series are covered under the VFD-24 (sometimes searched as VFD 24) — DWR is the base series, WRK and MRK are the SR (special rack) variants. If you're running any of these three frames in a 24U configuration, this is the correct door SKU.

Integration & Compatibility

The VFD-24 is designed as a direct accessory for Middle Atlantic's DWR, WRK, and MRK rack series in the 24U (24 rack unit) configuration. It does not require additional hardware beyond what the rack frame already provides for door mounting. It is not compatible with other rack depths, brands, or non-matching series. If your installation uses a different rack unit count or a different Middle Atlantic series, verify the correct VFD part number before ordering — Middle Atlantic produces vented front doors across multiple rack sizes, and fitment is series- and size-specific. For rack accessories and complementary enclosure components, confirm against your rack model number. When planning your rack layout, consult a rack and enclosure buying guide to match airflow strategy with equipment heat loads.

Frequently Asked Questions

Q: Which rack series does the VFD-24 fit?

A: The VFD-24 is compatible with Middle Atlantic DWR, WRK, and MRK series racks in the 24U (24 rack unit) configuration. It is not designed for other rack series or rack sizes.

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

A: The VFD-24 provides 25% open vent area across the door face, which supports passive convection airflow and allows active cooling systems to function without the door restricting airflow significantly.

Q: What are the physical dimensions of the VFD-24?

A: The VFD-24 measures 42.87 inches (108.9 cm) in height, 20.04 inches (50.9 cm) in width, and 1.39 inches (3.5 cm) in depth. Shipping weight is 19.85 lbs (9 kg).

Q: What finish does the VFD-24 have?

A: The VFD-24 has a textured black powder coat finish, which matches the factory finish on compatible Middle Atlantic rack series.

Q: Can the VFD-24 be used on racks from other manufacturers?

A: No. The VFD-24 is engineered specifically for Middle Atlantic DWR, WRK, and MRK series frames in 24U configurations. It is not a universal-fit door and will not align correctly on other manufacturers' rack frames.

Q: Is additional mounting hardware required to install the VFD-24?

A: The VFD-24 is designed to mount directly to compatible Middle Atlantic rack frames using the existing door hinge points on those series. No additional hardware beyond what the rack already provides is required for installation.

The VFD-24 is one of those parts that seems obvious until you order the wrong one — I've seen integrators grab a vented door from a different series and spend an hour figuring out why the hinge points don't line up. This door is cut for the DWR, WRK, and MRK frames at 24U, full stop. The 25% open area spec tells you something real: you're not getting the thermal performance of a fully open rack, but you're getting enough airflow relief that a moderately loaded 24U rack with a fan tray won't cook itself. That's the practical trade-off the VFD-24 is built around.

Technical Highlights:

• 25% Vent Open Area: Enough open surface to support active fan trays pulling heat rearward — not equivalent to an open-frame rack, but meaningfully better than a solid door, which can trap heat and force thermal throttling on sensitive equipment.
• 1.39 in Door Depth: Adds less than an inch and a half to the front clearance requirement. In closets where you're working with 24–30 inches of front access, that shallow profile keeps the aisle usable after the door is installed.
• Textured Powder Coat Finish: Holds up to repeated door cycles in active equipment rooms better than a painted surface. The texture is also forgiving on minor contact marks from cables and tools during maintenance — important in installations where multiple technicians access the rack.

Deployment Considerations:

• Verify your exact rack series before ordering — the VFD-24 covers DWR, WRK, and MRK at 24U, but Middle Atlantic's VFD lineup spans multiple sizes and series. A mismatch on series means the door won't hang correctly regardless of the RU count.
• At 25% open area, this door is not a substitute for active cooling in high-density configurations. If your 24U rack is running near thermal limits with dense NVR or switching gear, pair this door with a rack-mounted fan tray rather than relying on convection alone.

The VFD-24 is the right call for security operations head-ends and structured wiring closets where you need basic front protection and dust management on a DWR/WRK/MRK rack without eliminating airflow — particularly in multi-rack rows where aesthetics and consistent finish across frames matters to the end client.
