Middle Atlantic 25SP/27D Multibay BGR LRD - BGR-2527LRD

Middle Atlantic BGR-2527LRD 25RU Seismic-Rated Open-Frame AV Rack

Overview

The Middle Atlantic BGR-2527LRD is a 25-rack-unit, 27-inch-deep open-frame steel rack engineered for AV, security, and IT infrastructure where structural integrity under load — and in seismic zones — is a real design requirement, not an afterthought. At a UL-listed load capacity of 3,000 lbs and a seismic load rating of 1,175 lbs, this is the frame you specify when the gear inside it is expensive, mission-critical, or both. The BGR-2527LRD (often searched as BGR 2527LRD) ships as a frame-only configuration, giving integrators the flexibility to populate it with the exact cable management, shelving, and power distribution the project demands.

Built in the USA and fully TAA-compliant, this rack is a direct fit for federal, healthcare, and government facility projects where country-of-origin documentation matters at procurement. The HCAI (formerly OSHPD) seismic certification — under OSHPD number OPM-0444-13 — means it meets California's stringent hospital and critical-care facility standards, a spec few racks carry without additional engineering sign-off. For a broader look at Middle Atlantic rack and enclosure products, the full line covers everything from shallow-depth credenzas to deep server frames.

Key Features

• 25 RU / 43.88 in usable height: 25 rack units of usable space covers a dense NVR stack, a managed PoE switch, a UPS, and patch panels without running out of vertical real estate. The 43.88-inch usable height (111.5 cm) is the actual rail-to-rail measurement — plan your U-count against this, not the nominal chassis height.
• 3,000 lb UL-listed load capacity: This is a verified UL listing, not a marketing claim. A fully loaded rack of dense 1U servers or NVR appliances rarely exceeds 1,500 lbs; the 3,000 lb rating gives you a 2:1 safety margin and satisfies most structural sign-off requirements in commercial and institutional installs.
• 27 in total depth / 24.4 in usable depth: The 24.4-inch usable depth (62 cm) accommodates most 1U and 2U rack-mount appliances — standard NVRs, switches, and UPS units run 18–24 inches deep. Verify your deepest chassis before spec'ing; anything over 23 inches will be tight on cable dressing behind the unit.
• Seismic-rated at 1,175 lbs: The seismic load rating is independently certified under HCAI/OSHPD (OPM-0444-13), covering California hospital and critical-facility seismic zones. For projects outside California, this certification is broadly accepted by AHJs as evidence of engineered seismic compliance — it simplifies plan check, especially in Seismic Design Categories D and E.
• Forward rackrail configuration: The forward rackrail positions mounting points at the front of the frame, leaving the rear completely open for rear-access cabling, ventilation, and equipment with rear-facing I/O. This is the right choice when you need unobstructed rear cable runs — common in security head-end rooms where camera and alarm homerun cables enter from behind.
• Gangable construction: Multiple BGR frames can be ganged side-by-side into a unified multi-bay installation without gaps or misalignment. In large security operations centers or network closets where a single 25RU frame isn't enough, gangability eliminates the dead space and structural compromise that comes from lining up independent racks.
• 25mm x 150mm swing handles: The oversized swing handles aren't decorative — they allow safe two-person transport of a loaded or partially loaded frame. At a shipping weight of 104 lbs empty, you need a solid grip point for safe positioning during install.
• Black wrinkle powder coat finish: Wrinkle powder coat is more durable than smooth paint in high-traffic equipment rooms — it resists scratching during cable pulls and equipment swaps and doesn't show handling marks the way gloss finishes do. The all-black treatment also reduces light reflection in darkened NOC and SOC environments.
• TAA-compliant, made in the USA: Federal, state, and SLED projects with TAA requirements can spec this frame without a waiver. Country of origin is USA per the manufacturer's Federal Ops documentation — verifiable for GSA schedule and government contract procurement.
• Forward compatible: The BGR frame is designed to accept Middle Atlantic's forward-compatible accessory ecosystem — meaning future upgrades to cable management, vertical power strips, and mounting accessories won't require replacing the frame itself.

Integration and Compatibility

The BGR-2527LRD accepts standard 19-inch rack-mount equipment on its forward rackrails. With a 23-inch overall width (58.4 cm) and 19-inch panel width, it fits within standard equipment room floor plans and pairs naturally with open-frame and enclosed rack systems from the same platform. The gangable design means this unit can anchor a multi-bay row in a security head-end, network operations center, or large AV equipment room. Because it ships as a frame only, integrators sourcing complementary components — rack accessories including shelves, blanks, and cable managers — can configure the interior precisely for the application rather than working around pre-installed hardware.

For deployments pairing this rack with active network infrastructure, plan your PoE switch and power distribution layout around the 24.4-inch usable depth. The open rear makes it straightforward to route structured cabling homerun bundles directly into the frame from a raised floor or overhead cable tray. Review the rack selection and sizing guide if you're deciding between open-frame and enclosed configurations for this application.

Frequently Asked Questions

Q: Is the BGR-2527LRD TAA-compliant and eligible for federal procurement?

A: Yes. The BGR-2527LRD is TAA-compliant and manufactured in the USA, per the manufacturer's Federal Ops country-of-origin documentation. It is suitable for GSA schedule and federal contract procurement without a TAA waiver.

Q: What is the seismic certification on the BGR-2527LRD?

A: The BGR-2527LRD carries HCAI (formerly OSHPD) seismic certification under OSHPD number OPM-0444-13, with a seismic load capacity of 1,175 lbs (533 kg). This certification meets California hospital and critical-facility seismic standards and is broadly accepted by AHJs in other high-seismic regions.

Q: Does the BGR-2527LRD come with a rear door?

A: No. The BGR-2527LRD is an open-frame rack with no rear door. This is intentional for applications where rear cable access and airflow are priorities. If a rear door is required, a different enclosure in the Middle Atlantic line should be specified.

Q: What is the actual usable depth for rack-mount equipment?

A: Usable depth is 24.4 inches (62 cm). Total external depth is 27 inches. Most 1U and 2U rack-mount NVRs, switches, and UPS units fit comfortably; verify that any chassis deeper than 23 inches leaves adequate room for rear cable dressing.

Q: Can multiple BGR-2527LRD frames be ganged together?

A: Yes. The BGR-2527LRD is designed to be gangable — multiple frames can be installed side-by-side to create a continuous multi-bay rack row without gaps or structural compromise.

Q: What is the load capacity of the BGR-2527LRD?

A: The UL-listed load capacity is 3,000 lbs (1,360.8 kg). The seismic load capacity is separately rated at 1,175 lbs (533 kg) under the HCAI/OSHPD certification.

The spec I keep coming back to on the BGR-2527LRD is the dual load rating: 3,000 lbs UL-listed for static load and 1,175 lbs for seismic. Those are two different structural conversations, and having both independently certified on a single frame is what makes this unit the go-to for hospital and government security head-end rooms where the AHJ will ask for documentation on both.

Technical Highlights:

• 3,000 lb UL Load Rating: Verified UL listing — not a manufacturer claim. Most commercial NVR and switch stacks land well under 1,500 lbs loaded, so this rating provides genuine structural margin and simplifies sign-off on projects with formal load documentation requirements.
• HCAI/OSHPD Seismic Certification (OPM-0444-13): The 1,175 lb seismic capacity under OSHPD number OPM-0444-13 is one of the more rigorous seismic certifications available on a commercial rack. California hospital projects won't need a separate structural engineering review — the OPM number is the documentation.
• 24.4 in Usable Depth + Open Rear: The forward rackrail design leaves the full rear of the frame open. In a security head-end where you're landing dozens of homerun cables, that unobstructed rear access isn't a convenience — it's how you keep the install clean and maintainable.

Deployment Considerations:

• Frame-only configuration means budgeting separately for shelves, blanks, vertical cable managers, and power strips. This is a feature if you're specifying a custom interior, but factor the accessory cost into your project BOM from the start.
• At 104 lbs shipping weight empty, a two-person lift is required for safe positioning. The 25mm x 150mm swing handles are sized for this, but plan your installation sequence — getting the frame into a tight IDF or server closet before loading it is significantly easier than the reverse.

The BGR-2527LRD is the right specification call for California hospital security infrastructure projects, federal facility equipment rooms, and any commercial installation where the structural engineer or AHJ will require both static load documentation and a seismic certification number at permit review.
