Middle Atlantic Multibay BGR Series Rack with Rear Door 45 Rack Units (78-3/4IN. ) 27IN. - BGR-4527

Middle Atlantic BGR-4527 45U Floor-Standing AV/Security Rack with Rear Door

Overview

The BGR-4527 is a 45U, 27-inch-deep floor-standing steel rack designed for dense security and AV equipment installations where load capacity, seismic certification, and long-term serviceability are non-negotiable. At 3,000 lbs UL-rated load capacity and a 24.4-inch usable depth, this frame handles heavy NVR stacks, PoE switch banks, and UPS units without flex. The rear door and 25mm x 150mm swing handles make front-and-rear access straightforward in tight equipment rooms. Gangable construction lets you expand laterally without buying a new frame — the BGR-4527 pairs directly with other BGR-series bays when your footprint grows. TAA compliant and manufactured in the USA, it satisfies federal procurement requirements out of the box.

Compatibility

Built around a standard 19-inch EIA panel width, the BGR-4527 accepts any 19-inch rack-mount equipment: PoE and managed network switches, NVRs, patch panels, PDUs, KVM drawers, and cable management accessories. The forward rackrail configuration is compatible with Middle Atlantic BGR-series accessory panels, blanks, and fan trays. The gangable design integrates directly with other Middle Atlantic BGR-series racks for multi-bay runs. The seismic rating (OSHPD OPM-0444-13, HCAI formerly OSHPD) qualifies it for California hospital and healthcare facility deployments under HCAI requirements — confirm your facility's jurisdiction tier before specifying. This is a floor-standing rack enclosure frame-only configuration; doors, side panels, and cable managers are ordered separately.

Installation Notes

Shipping weight is 152 lbs — plan for two-person placement. Usable interior depth is 24.4 inches (not the full 27-inch frame depth), so measure your deepest shelf or slide-out component against that figure before ordering. The seismic load capacity is 1,175 lbs — roughly 40% of the static UL rating — which is the governing number for UPS and high-density power equipment in seismically active zones. Frame-only configuration means no side panels are included; budget for those separately if the install environment requires enclosure. The forward rackrail positions equipment toward the front of the bay, which suits front-access-heavy gear but requires rear cable management planning for pass-through cabling to rear-mount devices. Black wrinkle powder coat finish is consistent across the BGR series for matched multi-bay deployments.
