Middle Atlantic Solid Front Door Fits 12 Space Black Textured Powder Coat Finish - FD-12

Middle Atlantic FD-12 Solid Front Door for 12U DWR Series Racks

Overview

The Middle Atlantic FD-12 is a solid front door panel designed to fit 12-space (12U) enclosures in the DWR rack series. At 21.87 inches tall, 20.04 inches wide, and only 1.39 inches deep when closed, it adds a clean, finished face to open-bay racks without consuming meaningful depth in tight equipment rooms or AV closets. The textured black powder coat finish matches standard Middle Atlantic rack aesthetics, and the included keylock keeps gear secured against casual access — useful in shared-access IDF closets, retail back-of-house equipment rooms, and school AV installations where the rack is accessible to non-technical staff.

If you're searching for this model, note it's also referenced as FD 12 in some procurement systems.

Key Features

• 12U / 12-Space Capacity: Spans exactly 12 rack units — if your DWR enclosure is populated with 12U of gear and you need a door that covers it cleanly, this is a direct fit. No trimming, no adapter plates.
• Textured Black Powder Coat Finish: The finish matches the standard DWR rack family surface treatment. In installations where the rack is client-visible — conference rooms, lobby AV closets, reception desks — a consistent finish matters more than it sounds. Bare metal mismatches look unfinished to clients and facilities managers.
• Keyed Lock Included: The integrated keylock provides basic physical access control without a separate purchase. This isn't a high-security barrier, but it's sufficient to prevent a curious employee from pulling cables or powering down equipment. For environments requiring stricter access control, pair with a locking rack enclosure rather than relying on the door lock alone.
• Shallow Profile — 1.39 Inches of Added Depth: The door adds only 1.39 inches (3.5 cm) to the front of the rack. In congested equipment rooms or shallow-depth AV closets where every inch counts, that's a meaningful spec. Verify your front clearance before ordering if the rack sits close to a wall, door jamb, or cable management arm.
• Precise Panel Dimensions: At 21.87 inches tall and 20.04 inches wide (55.6 cm × 50.9 cm), the FD-12 is sized to the DWR series standard. These dimensions are not universal — confirm your rack model against the DWR base series before purchasing if you're retrofitting an existing enclosure.
• DWR Series Compatibility: Designed specifically as a replacement or add-on door for Middle Atlantic DWR enclosures. If your rack is from a different Middle Atlantic series (WRK, BGR, etc.) or a third-party manufacturer, this door is not guaranteed to fit — check your rack model number against the DWR series spec sheet.

Integration and Compatibility

The FD-12 is engineered for the Middle Atlantic DWR rack series. It is not a universal fit. Before ordering, verify that your rack enclosure is a DWR-series unit. The door mounts to the front of the enclosure and is intended as a factory-matched accessory, not an aftermarket universal panel. For installations where front ventilation is a concern, note that this is a solid door — it does not include perforations or venting. If your rack dissipates heat through the front face, a vented door variant would be more appropriate. For network switches, power distribution units, or other heat-generating equipment, factor airflow into your door selection before committing to a solid panel.

Integrators sourcing this as a replacement door for an existing DWR rack should confirm the rack's unit height matches the 12U door spec. A 12U door on a 15U or 18U enclosure leaves the top portion of the rack open — aesthetically inconsistent and potentially a dust or security issue in sensitive environments.

Frequently Asked Questions

Q: What rack series is the FD-12 compatible with?

A: The FD-12 is designed for Middle Atlantic DWR series enclosures. It is not a universal rack door and is not guaranteed to fit other Middle Atlantic series or third-party racks.

Q: Does the FD-12 include ventilation or airflow cutouts?

A: No. The FD-12 is a solid door with no perforations or ventilation slots. If your equipment requires front-face airflow, select a vented door variant instead.

Q: What are the exact dimensions of the FD-12?

A: The door measures 21.87 inches tall, 20.04 inches wide, and 1.39 inches deep (55.6 cm × 50.9 cm × 3.5 cm).

Q: Is a lock included with the FD-12?

A: Yes. The FD-12 includes an integrated keylock for basic physical access control.

Q: Will the FD-12 work on a rack that is not 12U in height?

A: No. The FD-12 is sized for 12-space (12U) enclosures. Installing it on a taller or shorter rack will result in a mismatch — either leaving rack space exposed or the door overhanging the enclosure.

Q: What finish does the FD-12 have?

A: Textured black powder coat, consistent with the standard DWR series rack finish.

The detail I always check first on a rack door is the depth add — and the FD-12 comes in at just 1.39 inches. In a lot of the IDF closet builds I've worked on, that's the difference between the door clearing a wall-mounted patch panel or fouling it. For a 12U DWR enclosure, this is the door you order when you need a finished, locked front without blowing your front-clearance budget.

Technical Highlights:

• 1.39-inch door depth: Adds only 3.5 cm to the rack's front footprint — workable in tight closets where standard swing-out doors create clearance conflicts with adjacent walls or cable trays.
• 21.87 × 20.04-inch panel: Dimensioned precisely to the 12U DWR series standard, so there's no field-fitting or shimming required on a matched enclosure.
• Integrated keylock: Eliminates a separate lock purchase and keeps the front face clean — no padlock hasp, no visible hardware gap. Sufficient for deterrence in low-risk shared-access spaces.

Deployment Considerations:

• This is a solid door — zero airflow through the front panel. If your 12U of gear includes high-watt switches, amplifiers, or dense compute, verify your rack's thermal design routes exhaust through the rear or top before locking in this door choice.
• DWR-series fit only. If you're replacing a door on an older or different Middle Atlantic enclosure, pull the rack model number and cross-reference against the DWR series spec sheet before ordering — Middle Atlantic has produced multiple rack families over the years, and door mounting patterns are not interchangeable across all of them.

The FD-12 is the right call for finished, client-visible 12U DWR rack deployments in conference rooms, reception areas, and AV closets where aesthetics and basic access control matter but the rack isn't running thermally demanding gear.
