Middle Atlantic FM Rack 12RU 27D A3 GR CG Solid Door - FMR-1227A3GC

Middle Atlantic FMR-1227A3GC 12RU Forum Series Side Rack Enclosure

Overview

The Middle Atlantic FMR-1227A3GC is a 12-rack-unit Forum Series side rack built for AV integration, security operations, and collaboration suite deployments where finished aesthetics matter as much as structural integrity. At 27 inches deep with a 300 lb weight capacity and an Asian Night HPL exterior, this enclosure is engineered for permanent installations in boardrooms, command centers, and huddle spaces — not the utility closet. The FMR-1227A3GC ships TAA-compliant and US-manufactured, making it a straightforward choice for federal, state, and education procurement where country-of-origin documentation is required.

Part of Middle Atlantic's Forum rack line, this unit bridges the gap between furniture-grade presentation and functional rack infrastructure. If you're specifying equipment for a structured rack enclosure deployment and need something that won't look out of place in a client-facing space, the FMR-1227A3GC is worth a close look.

Key Features

• 12 RU Capacity in a Compact Footprint: Twelve rack units in a 28-inch-tall chassis (31.5 inches with casters) gives you room for a UPS, patch panel, and several 1U or 2U devices without occupying a full-height floor rack. Right-sized for side-car deployments next to a lectern or credenza.
• 300 lb Weight Capacity: The steel internal structure handles 300 lbs of gear — enough for a dense AV or NVR stack including power distribution and cable management. You won't outgrow this structurally.
• 21.4-Inch Usable Depth: Total depth is 27 inches; usable rack depth is 21.4 inches. That 5.6-inch difference accounts for the forward rackrail, door, and rear clearance — plan your deepest chassis (switchers, UPS units) against that 21.4-inch usable figure, not the nominal 27.
• Forward Rackrail Design: Equipment mounts to a forward-positioned rackrail, keeping the front panel flush and accessible while maintaining rear cable routing space. Simplifies adds-and-changes without pulling the unit from the wall.
• HPL Exterior in Asian Night / Graphite: High-pressure laminate finish holds up to daily contact in high-traffic environments and cleans without refinishing. The Asian Night colorway coordinates with Graphite-tone AV furniture — a practical consideration when this rack sits in view of meeting participants.
• 25mm × 150mm Swing Handle: The ergonomic swing handle folds flat when not in use, keeping sightlines clean, and extends for repositioning the unit during installation or reconfiguration. At a shipping weight of 152.5 lbs fully packaged, you'll want this handle.
• Monitor Mounting Support: The FMR-1227A3GC supports monitor mounting — useful in control room or operator station configurations where a display needs to be co-located with rack gear rather than wall-mounted separately.
• Two Fan Openings (4.5-inch): Dual 4.5-inch fan openings provide thermal management flexibility for populated racks running compute-intensive or always-on equipment. Fan modules are field-installable; plan airflow front-to-back to avoid hot spots in densely loaded configurations.
• Forward Compatible Design: The Forum Series' forward-compatible architecture means accessories, panels, and expansion components designed for the platform integrate without retrofit complications. Protects the installation investment as the system grows.
• TAA Compliant, US-Manufactured: Federal Operations country of origin is US, and the unit carries TAA compliance — both required for GSA Schedule, DHS, DoD, and many state/local government contracts. Verify your specific contract vehicle requirements, but the compliance groundwork is in place.
• Caster-Ready Height: At 28 inches without casters and 31.5 inches with, the unit stays under standard ADA and countertop heights when casters are added, maintaining accessible reach to front-panel controls and connections.

Integration and Compatibility

The FMR-1227A3GC is designed as a side rack component within Middle Atlantic's Forum Collaboration Suite ecosystem. It integrates with Forum Series lecterns, credenzas, and AV furniture using the platform's forward-compatible mounting interface. The 12 RU capacity suits deployments pairing a managed PoE switch, NVR, UPS, and patch panel in a single contained unit. The forward rackrail accepts standard EIA-310 rack equipment; verify chassis depth against the 21.4-inch usable figure before ordering deep 4U or 6U appliances. The HPL finish is available in Asian Night (Graphite colorway), which coordinates with Middle Atlantic's broader Forum furniture line for matched installations. For larger deployments requiring more rack space, Middle Atlantic offers deeper and taller Forum variants within the same series — the FMR-1227A3GC is optimized for 12 RU side-car configurations, not as a primary equipment rack in large rack rooms. Consult a rack enclosure guide to match unit count and depth to your equipment list before finalizing the spec.

Frequently Asked Questions

Q: Is the Middle Atlantic FMR-1227A3GC TAA compliant?

A: Yes. The FMR-1227A3GC is TAA compliant and manufactured in the United States, satisfying procurement requirements for federal, state, and local government contracts that mandate TAA compliance and domestic origin.

Q: What is the usable rack depth of the FMR-1227A3GC?

A: The usable depth is 21.4 inches (54.4 cm). The total enclosure depth is 27 inches, but the forward rackrail, door, and rear clearance account for the difference. Spec your deepest chassis against 21.4 inches, not 27.

Q: What is the weight capacity of this rack?

A: The FMR-1227A3GC supports up to 300 lbs (136 kg) of installed equipment, sufficient for fully populated AV and security equipment stacks including UPS units, NVRs, and switching hardware.

Q: Does the FMR-1227A3GC support fan cooling?

A: Yes. The enclosure has two 4.5-inch fan openings for active cooling. Fan modules are not included by default — they are field-installed as needed depending on heat load. Plan airflow direction before populating the rack.

Q: Can the FMR-1227A3GC be used with casters?

A: Yes. The unit is caster-compatible, bringing total height to 31.5 inches (80 cm) from 28 inches (71.1 cm) without casters. Casters are a separate accessory — confirm compatibility with Middle Atlantic's Forum Series caster kits.

Q: What finish and color is the FMR-1227A3GC?

A: The enclosure uses a high-pressure laminate (HPL) exterior in the Asian Night colorway, which coordinates with Graphite-tone AV furniture. HPL is durable, cleanable, and appropriate for client-visible installations.

The FMR-1227A3GC is a product I recommend specifically when the rack is going into a room where the client or end user will see it. That 300 lb capacity in a 12 RU chassis with an HPL exterior is not an accident — Middle Atlantic engineered this for side-car deployments in collaboration suites and boardrooms where a black steel utility rack would look out of place. The 21.4-inch usable depth is the number integrators most often miss on this model; the nominal 27-inch spec sounds generous until you're trying to fit a deep UPS or video distribution chassis.

Technical Highlights:

• 21.4-in Usable Depth: 5.6 inches of the 27-inch total depth is consumed by the forward rackrail, door panel, and rear clearance — always size equipment against 21.4 inches or you'll be ordering shorter chassis after the fact.
• 300 lb Structural Capacity: The steel internal frame handles fully loaded configurations. A typical build — 1U PoE switch, 1U NVR, 1U patch panel, 2U UPS — lands well under the ceiling, but it's good to have headroom when clients inevitably add gear post-installation.
• Dual 4.5-in Fan Openings: Two fan cutouts give you airflow options without field modification. If the rack will run 24/7 compute load (NVR, server), install fan modules at commissioning — retrofitting cooling after the unit is populated is significantly more difficult.

Deployment Considerations:

• The swing handle (25mm × 150mm) is genuinely useful at 152.5 lbs shipping weight — position the unit before final wiring, not after, and confirm doorway clearance at the 25.75-inch width before delivery day.
• TAA compliance is verified for this SKU and the US manufacturing origin is documented, but always pull the current compliance letter for your specific contract vehicle — verbal confirmation is not sufficient for government procurement audits.

This rack is the right spec for a CCTV and AV control node in a finished executive boardroom or higher-education collaboration suite — where the integrator needs structural capability and a surface that doesn't require a furniture panel to hide it from the room.
