Middle Atlantic BGR-4127 41U Floor-Standing AV/Security Rack with Rear Door
Overview
The BGR-4127 is a 41-rack-unit, 27-inch-deep floor-standing steel enclosure from Middle Atlantic's Middle Atlantic BGR Series rack line. It targets enterprise AV, physical security control rooms, and datacenter-edge deployments where structural integrity and density matter equally. At a UL-rated 3,000 lb static load capacity, this rack handles fully populated NVR shelves, dense patch panels, and heavy UPS units without flex — the kind of load tolerance that lets you plan a full rack build without calculating weight margins on every shelf. The 41 RU height delivers 71.88 inches of usable panel space, and the 24.4-inch usable depth accommodates most 1U/2U network video recorders, servers, and managed switches without interference from the rear door. The rear door is included in the Frame Only configuration — no additional door kit required. This unit ships at 150 lbs; plan accordingly for lift equipment on multi-rack installs.
Compatibility
The BGR-4127 accepts any standard 19-inch EIA-310 rackmount equipment via its forward rackrail system. The Forward Compatible designation means it pairs with Middle Atlantic's BGR accessory ecosystem — side panels, roof panels, casters, and PDU brackets designed for this frame series. The Gangable construction allows multiple BGR units to be bolted side-by-side in multi-bay configurations, which is the standard approach in larger rack system deployments such as security operations centers or broadcast equipment rooms. TAA Compliant status makes it eligible for US federal procurement. Seismic certification to HCAI (formerly OSHPD) standard under number OPM-0444-13 qualifies it for healthcare facility installations in California seismic zones — a hard requirement that most generic racks cannot meet. The seismic load rating is 1,175 lbs under that certification, separate from the static 3,000 lb UL figure. For integrators building out power and UPS infrastructure alongside security gear, the frame's depth and load rating support 2U rackmount UPS units without modification.
Installation Notes
The BGR-4127 ships as a frame-only unit — no shelves, PDUs, blanks, or cable management are included. The 25mm x 150mm swing handles are factory-installed on the frame. Finished in Black Wrinkle Powder Coat; surface is not paintable post-delivery without prep. Country of origin is USA. Verify floor load tolerance before deployment: 3,000 lbs static load on a fully populated rack concentrates significant point load at the four leveling feet positions. The 23-inch external width is the planning dimension for side-by-side gangable arrays; confirm aisle clearance before ordering multiple units.
