Middle Atlantic FMR-1627E1MS 16RU Forum Series Floor-Mount Rack Enclosure
The Middle Atlantic FMR-1627E1MS is a 16-rack-unit floor-standing enclosure from the Forum Collaboration Suite line, built around a 27-inch total depth and an HPL (High-Pressure Laminate) Kensington Maple exterior — a finish choice aimed squarely at boardrooms, command centers, and AV-integrated security operations rooms where the rack sits in open view rather than a back-of-house closet. At 300 lbs rated load capacity and a 25.75-inch width, it handles a fully loaded equipment stack without flex or deflection concerns.
Overview
Forum-series enclosures from Middle Atlantic's rack and enclosure line are designed to bridge the gap between utilitarian server-room racks and furniture-grade AV credenzas. The FMR-1627E1MS delivers a 21.4-inch usable interior depth — enough to seat most 1U/2U network switches, NVRs, amplifiers, and media processors without rear-panel crowding. The enclosure ships on casters, standing 38.5 inches tall with them installed (35 inches without), making it rollable during installation and lockable in final position. TAA compliance is confirmed, making this eligible for federal and government-funded deployments that require US-origin equipment.
Key Features
- 16 Rack Units, 21.4" Usable Depth: Sixteen RU of usable space accommodates a mix of 1U and 2U gear — think NVR, PoE switch, UPS, and patch panel in a single enclosure. The 21.4-inch usable depth (out of 27 inches total) leaves clearance behind equipment for cable routing without forcing tight bends on fiber or Cat6 runs. See our rack enclosure selection for alternative depths if your deepest component exceeds 20 inches.
- 300 lb Weight Capacity: A fully loaded 16RU rack with a 2U UPS, 2U NVR, PoE switch, and patch panel can easily exceed 150 lbs. The 300 lb rating gives substantial headroom — relevant when building out a dense surveillance or AV control stack that grows over time rather than being designed once and frozen.
- HPL Kensington Maple Finish with Silver Gray Magnesium Accents: HPL (High-Pressure Laminate) is a furniture-grade surface material that resists scratching and moisture better than painted steel or vinyl wrap. In conference rooms, executive briefing centers, or integrated security operations desks, this matters — the enclosure looks intentional rather than industrial. The Silver Gray magnesium accent panels complement light wood tones without demanding a full custom millwork surround.
- Forward Rackrail Configuration: The Forward Rackrail design positions rack rails toward the front of the enclosure, maximizing usable rear depth for cable management and power distribution. This is the right geometry for AV and security rack builds where rear-panel access and cable dressing matter as much as front-panel operation. Pair with a rack-mount PDU mounted at the rear rail for clean power runs.
- 25mm × 150mm Swing Handles: Integrated swing handles on the sides mean two-person lifts and repositioning during installation don't require improvised grip points. On a unit shipping at 157.5 lbs, this is a real ergonomic detail — not decorative.
- Two 4.5" Fan Openings: The enclosure includes two 4.5-inch fan openings for active ventilation. Thermal management in a 16RU stack running NVR storage plus network switching is non-trivial — these openings allow field-installed fan trays (sold separately) to move air through the enclosure without cutting custom holes. Plan your fan tray order alongside the rack if the equipment load generates significant heat.
- Monitor Mounting Support: The FMR-1627E1MS supports monitor mounting, allowing a display to be integrated directly into the enclosure structure. In security operations and AV presentation rooms, this eliminates the need for a separate monitor stand or wall-arm adjacent to the rack — keeping the installation footprint compact.
- Forward Compatible Design: Forward compatibility means this enclosure is engineered to accept future Middle Atlantic Forum-series accessories and upgrades — side panels, top caps, and integration modules — without requiring a full enclosure replacement. For installations that evolve over a 5–10 year lifecycle, that matters when budgeting for phased upgrades rather than forklift replacements.
- TAA Compliant, US-Origin: Federal country-of-origin is confirmed as the United States. TAA compliance is verified for this SKU, making FMR-1627E1MS suitable for GSA schedule purchases, DoD installations, and federally funded education or public safety projects where Buy American and TAA provisions apply.

Integration and Compatibility
The FMR-1627E1MS integrates within the broader Middle Atlantic Forum Collaboration Suite ecosystem, accepting Forum-series accessory modules including side racks, top caps, and collaborative work surface attachments. The Forward Rackrail system is compatible with standard EIA 19-inch rack equipment — all mainstream NVRs, managed PoE switches, UPS units, and AV processors mount without adapter rails. The enclosure's 16RU capacity is well-matched to a mid-size surveillance head-end: a 4K 16-channel NVR (typically 2–4RU), managed switch (1RU), UPS (2–3RU), and patch panel (1RU) fit comfortably with space remaining for expansion. REACH and RoHS compliance (noted in source data as TAA/REACH) supports deployments in jurisdictions with environmental material restrictions.
Frequently Asked Questions
Q: Is the FMR-1627E1MS TAA compliant for government procurement?
A: Yes. The FMR-1627E1MS is confirmed TAA compliant with US country of origin, making it eligible for GSA schedule and federally funded projects subject to Trade Agreements Act requirements.
Q: What is the usable interior depth of the FMR-1627E1MS?
A: The usable interior depth is 21.4 inches (54.4 cm). The total enclosure depth is 27 inches — the difference accounts for the rack rail structure and rear frame. Plan your deepest components (NVRs, UPS units) against the 21.4-inch figure, not the overall 27-inch depth.
Q: How much equipment weight can the FMR-1627E1MS support?
A: The rated weight capacity is 300 lbs (136 kg). Shipping weight of the enclosure itself is 157.5 lbs (71.4 kg), so the structural margin for installed equipment is substantial across a fully loaded 16RU stack.
Q: Does the FMR-1627E1MS include ventilation for rack-mounted equipment?
A: The enclosure includes two 4.5-inch fan openings to accept field-installed fan trays. Active fan trays are not included in the base enclosure and should be ordered separately based on your equipment's thermal load.
Q: Can the FMR-1627E1MS accommodate a monitor?
A: Yes. The FMR-1627E1MS supports monitor mounting, allowing a display to be integrated directly into the enclosure. Specific monitor mount hardware compatibility should be confirmed against Middle Atlantic's Forum-series accessory catalog.
Q: What finish and material is the FMR-1627E1MS exterior?
A: The exterior is Kensington Maple HPL (High-Pressure Laminate) with Silver Gray magnesium accent panels. HPL provides a furniture-grade, scratch-resistant surface appropriate for visible installations in conference rooms, executive spaces, and integrated operations centers.
The FMR-1627E1MS is one I recommend specifically when the rack is going into a space where it will be seen — boardrooms, integrated security operations desks, executive briefing centers. The Kensington Maple HPL finish with Silver Gray accents isn't just cosmetic; it signals that this was a designed installation, not an equipment closet that got moved into the room. With 16RU and a 300 lb capacity, you have real headroom to build out a full surveillance or AV head-end without hitting the ceiling on space or structural limits.
Technical Highlights:
- 21.4" Usable Depth: Out of the 27-inch total footprint, you get 21.4 inches of clear equipment depth — enough for virtually any 1U/2U NVR, managed switch, or UPS without hitting the rear frame. That 5.6-inch difference isn't wasted; it's where your power and cable management lives.
- Dual 4.5" Fan Openings: Two fan openings at 4.5 inches each are sized for standard rack fan trays. In a loaded 16RU stack, passive convection alone won't cut it — spec the fan trays at order time, not after you're chasing a heat alarm in a live installation.
- TAA / US Origin: Federal country of origin is confirmed as the United States and TAA compliance is verified on this SKU. If you're quoting a government end-user or a project with federal funding strings, that's a line item you won't have to chase down later.
Deployment Considerations:
- At 157.5 lbs shipping weight, this enclosure requires two-person handling during delivery and positioning — the integrated 25mm × 150mm swing handles make grip straightforward, but plan for a two-person crew on install day. The caster-equipped height of 38.5 inches means it rolls under most standard ceiling heights without issue.
- Fan trays are not included. If your equipment stack includes power-hungry hardware — 16-channel 4K NVR with spinning drives, PoE switch under load, UPS charging — budget for active ventilation from day one. The openings are there; the fans are not.
This enclosure is the right call for a security operations or AV integration project where the rack sits in an occupied, visible space and the client expects the installation to look finished. It is not the right pick for a locked telecom room where a vented steel rack at half the price does the same job with no one watching.
