Middle Atlantic 19SP27D Multibay BGR Rack - BGR-1927

Middle Atlantic BGR-1927 19RU Open-Frame Floor Rack with Seismic Rating

The Middle Atlantic BGR-1927 is a 19RU, 27-inch-deep steel floor rack built for integrators who need a load-bearing, seismically rated enclosure without compromise. At 3,000 lbs UL-listed static load capacity and a verified OSHPD seismic rating (OPM-0444-13), this is the rack you specify when the AHJ asks for documentation — not just a rack you hope passes. It ships as a frame-only configuration, giving systems integrators a clean platform to build out precisely the way a project demands, whether that's a dense AV headend, a surveillance NVR stack, or a critical infrastructure comms closet.

Key Features

• 3,000 lb UL-Listed Load Capacity: The BGR-1927 is UL-listed for 3,000 lbs static load — not a manufacturer self-claim. That rating matters when local inspectors or insurance underwriters require third-party verification, and it reflects the robustness of the 11-gauge steel frame construction. For reference, a fully loaded 19RU rack with heavy UPS, NVR, and switching gear rarely exceeds 600–800 lbs; this rack has room for any realistic AV or security build.
• Seismic Rating — OSHPD OPM-0444-13: The BGR-1927 carries a verified HCAI (formerly OSHPD) seismic certification (OPM-0444-13) with a seismic load capacity of 1,175 lbs. If you're installing in California healthcare facilities, state government buildings, or any jurisdiction that enforces ASCE 7 seismic requirements, this number is what gets your submittal approved. It's not a marketing claim — the OPM number is on file and searchable.
• 19RU / 33.38 in Usable Height: Nineteen rack units of usable vertical space in a 37.38-inch overall height keeps the footprint compact. For a surveillance deployment, 19RU comfortably houses a 4U NVR, a 1U PoE switch, a 1U UPS management card, patch panels, and cable management with room to spare — no forced vertical sprawl.
• 27 in Depth / 24.4 in Usable Depth: The 27-inch nominal depth yields 24.4 inches of usable clearance front-to-rear. That's enough for deep 2-post or 4-post gear like full-depth servers, large-format UPS units, or high-port-count switches — which is why this rack sees wide deployment in both AV headends and enterprise security closets.
• Forward Rackrail Configuration: The front rackrail is the only rail shipped (frame-only). This suits 2-post-friendly NVRs, managed switches, and rack-mount UPS units that don't require rear rail support. If you need 4-post support for full-depth servers, Middle Atlantic offers compatible rear rail kits within the BGR family.
• Gangable Design: The BGR-1927 is gangable, meaning multiple units can be bolted side-by-side into a continuous multi-bay rack row. For large security operations centers or broadcast headends where horizontal expansion is planned, this eliminates the need to source a larger single enclosure — start with one bay, add laterally as the project grows.
• Forward Compatible Frame: The forward-compatible frame design accepts future Middle Atlantic accessories — power management, cable management, casters, leveling feet — without requiring frame replacement. That's a real long-term TCO consideration on a rack that may sit in service for 10–15 years.
• Rear Door Included: A rear door ships with the BGR-1927 (BGR-1927 frame-only configuration). In surveillance and AV installs, a rear door is the line between a cable-managed professional install and an exposed tangle. Rear access control also helps enforce clean separation between front-facing active gear and rear cable runs.
• 25mm x 150mm Swing Handles: The integrated swing handles are sized for practical use — not decorative. On a rack that can exceed 100 lbs empty (107 lb shipping weight), proper handles matter for positioning during installation, especially in tight IDF closets or equipment rooms without pallet access.
• Black Wrinkle Powder Coat Finish: The wrinkle powder coat is a commercial-grade surface treatment that resists scratching during installation better than smooth paint. On a floor rack that will have equipment slid in and out repeatedly over its service life, that durability is functional rather than aesthetic.
• TAA Compliant / Made in USA: The BGR-1927 is TAA-compliant and manufactured in the USA — a hard requirement for federal, state, and many municipal government contracts. If your project requires Buy American compliance or TAA-covered procurement under GSA schedules, this is the rack to specify without a waiver request.

Integration and Compatibility

The BGR-1927 accepts standard 19-inch rack-mount equipment on its forward rackrail. It integrates cleanly with network video recorders, managed PoE switches, rack-mount UPS units, and patch panels — the core components of a surveillance headend. The gangable design connects to other BGR-series bays for multi-rack deployments. For structured cabling and power distribution, Middle Atlantic's own rack accessories (PDUs, cable management arms, blanking panels) are forward-compatible with this frame. If you're planning a multi-rack security operations build, pair this with a rack power and cable management solution sized for the total RU count.

For projects requiring seismic documentation specifically, the OSHPD number OPM-0444-13 is the submittal reference — your structural engineer or AHJ will recognize it immediately. The HCAI/ASCE classification means this rack has been tested to the seismic performance requirements applicable to acute care hospital facilities, among the most stringent in the country.

If you're selecting between rack depths for a specific equipment stack, consult a rack selection guide to match usable depth to your deepest piece of gear — 24.4 inches of usable depth accommodates most commercial security and networking equipment, but full-depth servers at 28–30 inches will need a deeper frame.

The BGR-1927 is the rack I specify on projects where the AHJ won't accept a verbal commitment — that OSHPD number (OPM-0444-13) on the submittal closes the seismic conversation immediately. The 3,000 lb UL-listed load rating is also far beyond what any realistic 19RU security stack will impose, which means you're not engineering to the edge of the spec — you have genuine structural margin. For government and healthcare bids specifically, the TAA compliance and USA origin documentation are already built into the product, not a special-order variant.

Technical Highlights:

• Seismic Capacity 1,175 lbs (OPM-0444-13): HCAI/OSHPD certification is required by California HCAI for hospital and acute care projects — this rack has the number, which means no seismic engineering addendum needed for the rack itself.
• 3,000 lb UL Load Rating: Provides a 4–5x safety margin over a fully populated 19RU surveillance stack, so you're never near the structural limit even with high-density NVR and UPS gear.
• 24.4 in Usable Depth: Covers full-depth managed switches, enterprise-class NVRs, and most rack-mount UPS units without requiring a deeper (and taller) enclosure — keeps the install compact at 37.38 inches overall height.

Deployment Considerations:

• The frame-only configuration means no rear rails out of the box — confirm your NVR or switch vendor's mounting requirements before ordering; 2-post-friendly gear ships same day, 4-post gear may need a rear rail kit ordered separately.
• At 107 lbs shipping weight for an empty frame, plan for two-person positioning during installation, particularly in constrained IDF closets where pallet jack access is limited.

The BGR-1927 is the right call for California healthcare, federal government, and seismic-zone critical infrastructure deployments where documentation requirements are non-negotiable and structural margin matters — not a general-purpose rack for open office IT closets where a lighter frame would do the job at lower cost.
