Middle Atlantic BGR-4527-AV 45U Pre-Configured Pro AV Floor-Standing Rack
Overview
The BGR-4527-AV is a 45U, 27-inch-deep steel floor-standing rack pre-configured for Pro AV deployments where installation speed and long-term expandability matter. Rather than sourcing and assembling rack components individually, the BGR-4527-AV ships ready to populate — a direct time-saver on deadline-driven AV installs in boardrooms, control rooms, and equipment closets. The rack measures 83.23 in tall (23 in wide) with a usable height of 78.88 in across all 45 RU, and accepts standard 19-inch panel-width equipment throughout. A forward rackrail configuration keeps cabling and rear clearance accessible, while the included rear door provides physical security and a finished appearance. With a 3,000 lb static weight capacity, this frame handles dense AV amplifier, processor, and switching loads without flex concerns. The black wrinkle powder coat finish is consistent with Middle Atlantic's BGR line aesthetic for client-facing installs.
Compatibility
Accepts any standard 19-inch EIA-310 rack-mount equipment — AV processors, matrix switchers, amplifiers, UPS units, patch panels, and power distribution units up to the full 45 RU usable space. The 27-inch external depth yields 17.9 inches of usable depth, accommodating the majority of commercial AV gear; verify chassis depth on deep-draw amplifiers or server-class equipment before spec'ing. The BGR-4527-AV is forward-compatible with Middle Atlantic BGR accessories — side panels, casters, seismic kits, and ventilation options integrate without frame modification. Gangable design allows side-by-side deployment with additional BGR units where expanded rack footprint is needed. Compatible with Middle Atlantic power distribution and fan tray accessories designed for the BGR series.
Installation Notes
Shipping weight is 375 lbs — plan for mechanical lift assist or multi-person handling during positioning. Internal airflow capacity is rated at 276 CFM; supplement with active fan trays for high-density thermal loads concentrated in a small RU band. The 25mm x 150mm swing handles on the frame aid in positioning during install. The rear door is included; confirm door swing clearance (the rack is 23 in wide) against room layout before final placement. Forward rackrail configuration means equipment is mounted at the front rail — factor in cable management depth behind gear when calculating effective usable depth against the 17.9-inch spec.
