Middle Atlantic BGR-4532LRD 45U Open-Frame AV Rack — Frame Only
Overview
The BGR-4532LRD is a 45U, 32-inch-deep open-frame steel rack from Middle Atlantic's BGR series, built for high-density AV and security equipment installations where structural integrity, seismic compliance, and long-term expandability matter. At 3,000 lbs UL-rated load capacity with a 23-inch overall width and 29.4-inch usable depth, this frame handles fully loaded NVR shelves, patch panels, UPS units, and switchers without flex or racking — the kind of build-out that stays square after years of adds and swaps. The BGR-4532LRD ships as a frame-only unit, so you select the doors, side panels, and accessories your specific deployment requires rather than paying for hardware you won't use.
Compatibility
The BGR-4532LRD accepts standard 19-inch EIA-310 rack equipment across all 45U of usable height (78.88 inches usable). Forward rackrail positioning accommodates deep chassis — servers, NVR appliances, and UPS units — within the 29.4-inch usable depth. The rack is forward-compatible and gangable, meaning multiple BGR frames can be bolted together side-by-side for multi-bay installations without additional joining hardware kits. Compatible with Middle Atlantic's full BGR accessory ecosystem: doors, side panels, casters, leveling feet, roof/vent panels, and PDUs. Seismic rating meets HCAI (formerly OSHPD) requirements under certification OPM-0444-13, qualifying it for healthcare, California essential-services facilities, and other jurisdictions with ASCE seismic mandates — seismic load capacity is rated at 1,175 lbs (533 kg) under those conditions. TAA compliant and manufactured in the USA, satisfying federal procurement and GSA schedule requirements without additional documentation.
Installation Notes
Overall footprint is 23 inches wide by 32 inches deep — confirm floor cutout and aisle clearance before delivery; at 146 lbs shipping weight, two-person placement is standard. The frame-only configuration requires separate procurement of leveling feet or casters; plan rack stabilization before loading equipment. Swing handles (25mm x 150mm) are pre-installed on the frame. For seismic-compliant installations, anchor bolting must follow the OSHPD OPM-0444-13 certification requirements — verify with your structural engineer that the slab or raised-floor system meets the rated seismic load. No rear door is included or available in this SKU; factor that into cable management and airflow planning for the back of the rack.
