Middle Atlantic BGR-25SA27MDK-EA 25U Freestanding Rack Enclosure
Overview
The Middle Atlantic BGR-25SA27MDK-EA is a 25U, 27-inch deep freestanding rack enclosure built for AV integration, security control rooms, and IT infrastructure deployments where physical security and cable discipline matter as much as rack density. At 622.3 mm wide (standard EIA 19-inch rail spacing), 796.3 mm deep, and 1270 mm tall, this cabinet gives you the footprint of a mid-size rack with the structural integrity of a steel enclosure rated to 500 kg — roughly 1,100 lbs of installed gear before you need to think about weight limits. The BGR-25SA27MDK-EA ships with a plexiglass front door and steel side panels included, so you're not ordering hardware piecemeal to button up the enclosure after install. RoHS certification confirms materials compliance for deployments in environmentally regulated facilities.
Key Features
- 25U Rack Capacity: Twenty-five rack units in a 1270 mm tall cabinet gives you enough vertical space for a mid-to-large security or AV system — NVRs, servers, patch panels, KVM switches, and power distribution — without going to a full 42U floor cabinet that dominates the room. This is the sweet spot for a dedicated security closet or secondary equipment room.
- 500 kg Structural Rating: That's over 1,100 lbs of installed weight capacity — far beyond what most populated security racks will ever reach. Practically, this means the frame won't flex or rack-rail tolerance won't degrade as you add dense 2U or 4U equipment over time. Steel construction throughout delivers that load rating without relying on bracing add-ons.
- 27-Inch Depth (796.3 mm exterior, 620 mm inner): The 620 mm usable inner depth accommodates full-depth 1U/2U servers and high-density NVRs that typically run 450–550 mm deep, while still leaving rear cable management space. Shallow-depth enclosures (under 500 mm inner) force you to reconsider equipment selection; this one doesn't.
- Plexiglass Front Door with Key Lock: The plexi door gives you at-a-glance status visibility — indicator LEDs, drive activity, display panels — without opening the cabinet. The key lock on the front door controls physical access, which matters in shared facilities, multi-tenant environments, or anywhere with compliance requirements around equipment access. Black finish integrates cleanly in finished spaces.
- Steel Side Panels Included: Side panels ship with the unit, not as a separate line item. Steel side construction closes off the enclosure for cable tidiness and provides a degree of EMI containment — relevant when the cabinet is near sensitive audio or RF equipment.
- Rack Rails Included: Rails are part of the package. The 19-inch (48.3 cm) standard EIA rail spacing fits any standard rack-mount equipment without adapter kits. This matters at install time: you can rack gear the day the cabinet arrives.
- RoHS Compliant: RoHS certification verifies restricted substances compliance — required for deployments in EU markets and increasingly expected in public-sector and healthcare procurement specs. Confirms no cadmium, lead, mercury, or other restricted substances in the cabinet materials.
- 111.1 cm Inner Height (1111 mm usable): With 1111 mm of usable vertical space mapped across 25U, you get 44.4 mm per rack unit — consistent with standard 1U = 44.45 mm EIA spacing. No compressed or non-standard rack unit pitch to worry about when planning dense deployments.
Integration & Compatibility
The BGR-25SA27MDK-EA follows EIA-310 19-inch rack standards, making it compatible with the full range of Middle Atlantic rack accessories — including power distribution units, ventilation panels, cable managers, and blanking panels. Any standard 19-inch rack-mount equipment installs without modification. The 27-inch depth (27DP designation) positions this cabinet to house full-depth 1U and 2U equipment commonly found in security and AV rack enclosures — NVRs, managed PoE switches, patch panels, and UPS units. If you're planning the broader infrastructure around this cabinet, review a rack layout and cable management guide before committing to depth and unit counts; inner depth directly constrains your equipment selection. Pair this cabinet with a rackmount power distribution unit sized to your load — at 25U and 500 kg capacity, this enclosure can handle a fully populated system that will draw significant amperage. For deployments requiring active thermal management, the steel side panels are removable to allow side-entry airflow or fan panel installation; plan that before you populate the cabinet, not after.
Frequently Asked Questions
Q: What is the usable inner depth of the BGR-25SA27MDK-EA?
A: The inner depth is 620 mm (62 cm). The exterior depth is 796.3 mm. This accommodates most full-depth 1U and 2U servers and NVRs, which typically run 450–550 mm deep, while leaving room for rear cable routing.
Q: Does the BGR-25SA27MDK-EA include side panels and rack rails?
A: Yes. Steel side panels and rack rails are included with the unit. The front plexiglass door with key lock is also included. You do not need to order side panels or rails separately.
Q: What is the maximum weight capacity of the BGR-25SA27MDK-EA?
A: The rated maximum weight capacity is 500 kg (approximately 1,102 lbs). This is the structural load rating for installed rack equipment.
Q: Is the BGR-25SA27MDK-EA RoHS compliant?
A: Yes. The BGR-25SA27MDK-EA carries RoHS certification, confirming restricted hazardous substances compliance. This satisfies RoHS requirements for EU market deployments and public-sector procurement specifications that require materials compliance documentation.
Q: What rail spacing does the BGR-25SA27MDK-EA use?
A: Standard EIA 19-inch (48.3 cm) rail spacing. All standard 19-inch rack-mount equipment installs without adapters.
Q: Can the side panels be removed for airflow or ventilation panel installation?
A: The enclosure ships with steel side panels included. Side panels on rack enclosures of this type are typically removable to accommodate ventilation accessories or side-entry airflow configurations, though you should verify compatibility with specific Middle Atlantic ventilation accessories for this cabinet line before purchasing thermal management components.
The BGR-25SA27MDK-EA hits a practical sweet spot that integrators often overlook when speccing security closets: 25U gives you the density of a serious equipment deployment without committing to the floor-space and visual footprint of a 42U cabinet. The 500 kg structural rating means you're not budgeting rack space around weight limits — populate it fully and the frame stays in spec.
Technical Highlights:
- 620 mm Inner Depth: Full-depth NVRs and servers (typically 450–550 mm) fit with rear cable clearance intact — no equipment substitutions forced by a shallow cabinet.
- Steel Construction with Plexi Front Door: Steel side panels and frame deliver the 500 kg load rating; the plexiglass front door lets you monitor indicator LEDs and display panels without breaking the key-locked physical security boundary.
- RoHS Certification: Materials compliance is documented — relevant for government, healthcare, and EU-market deployments where procurement specs require it. Not a checkbox you want to chase after award.
Deployment Considerations:
- At 796.3 mm exterior depth, confirm your room clearance before ordering — you need at least 900–1000 mm total depth including rear door swing and cable egress clearance behind the cabinet.
- This enclosure does not include active cooling. In a fully populated 25U deployment with NVRs and dense switching, plan for a fan panel or top-mount exhaust unit; steel side panels provide some containment but passive airflow alone may be insufficient at high load densities.
This cabinet is well-matched for a dedicated security operations room or AV control environment where you need a mid-size, physically secured enclosure with documented materials compliance — not an open-frame rack in a shared IT closet.
