Middle Atlantic Multibay BGR Series Rack with Rear Door 45 Rack Units (78-3/4IN. ) 32IN. - BGR-4532

Middle Atlantic BGR-4532 45U Floor-Standing AV/IT Rack with Rear Door

Overview

The BGR-4532 is a 45U, 32-inch-deep floor-standing steel rack designed for dense AV, security, and IT deployments where load capacity and seismic compliance are non-negotiable. At 3,000 lbs UL-rated static load and seismic certification under OSHPD OPM-0444-13 (HCAI/ASCE), this is the rack to specify for California healthcare facilities, critical infrastructure, and any site governed by seismic codes — the 1,175 lb seismic load rating is the specific number to put on the submittal. The BGR-4532 ships as a frame-only configuration, giving integrators a clean starting point for custom equipment layouts without paying for pre-installed accessories that may conflict with existing hardware. TAA compliance makes it eligible for federal and government contract deployments. The Middle Atlantic rack catalog includes a broad range of enclosure depths and unit heights — the BGR-4532 occupies the 45U/32in position in the floor-standing rack enclosures category, suited for NVR stacks, managed switches, UPS units, and security head-end builds.

Compatibility

Built on a standard 19-inch EIA panel width, the BGR-4532 accepts any EIA-310-compliant rackmount equipment: NVRs, network switches, patch panels, power distribution units, KVM drawers, and AV signal processors. The 29.4-inch usable depth (from rail face to rear door interior) accommodates virtually all enterprise 1U–4U appliances, including deep 1U servers and full-depth network chassis. The rear door ships installed. The forward rackrail design is forward-compatible with Middle Atlantic BGR accessory mounting options. Gangable construction allows multiple BGR-4532 units to be bolted side-by-side for expanded multi-bay builds — relevant for security operations centers and large NVR/storage deployments. Pairs well with rackmount UPS and power distribution equipment and managed PoE switches in a consolidated head-end. For cable management and blanking panels, reference the rack accessories category for compatible Middle Atlantic add-ons.

Installation Notes

The BGR-4532 ships at 164 lbs — plan for a two-person lift or a lift device; the assembled rack with equipment load will exceed safe single-person handling well before reaching the 3,000 lb capacity. Dimensions are 23 in wide × 32 in deep × 82.88 in tall overall; the usable interior is 78.88 in tall by 29.4 in deep. Swing handles (25mm × 150mm) are factory-installed. Country of origin is USA. For seismic-anchored installs, the OSHPD number OPM-0444-13 is the reference for permitting in California HCAI-regulated facilities — confirm local AHJ requirements before finalizing the anchor pattern. The black wrinkle powder coat finish is scratch-resistant for field handling but not immune to sharp edge contact during equipment installation; use rail guards when sliding in heavy chassis.
