Middle Atlantic SRB-1-BGR-3224 – 1-Bay Seismic Riser Base for BGR Racks

Product Overview

The Middle Atlantic SRB-1-BGR-3224 is a one-bay seismic riser base designed for 32-inch deep BGR Series racks, sized at 24 inches high. It lets integrators complete field rough-in before the racks and enclosures arrive on site, keeping construction schedules moving on phased commercial projects. Once racks are set, the base doubles as a lower cable chase for passing cables between adjacent bays. Heavy-gauge welded steel construction supports seismic rack installation in code-regulated facilities.

Product Description

On large commercial AV and broadcast projects, equipment racks are often among the last items delivered, while electrical and low-voltage rough-in happens weeks earlier. The SRB-1-BGR-3224 solves that sequencing problem: the riser base anchors to the floor early in construction, allowing conduit stubs, floor penetrations, and cable pulls to be roughed in before the BGR enclosure ships. When the rack arrives, it mounts directly to the pre-installed base, reducing on-site labor and schedule risk. The base is part of Middle Atlantic's SRB Seismic Riser Base family, engineered specifically for the BGR Series of floor-standing AV racks; this model matches one bay of 32-inch deep BGR enclosures and stands 24 inches high. Beyond rough-in, the raised base functions as a lower cable chase, giving installers a protected path to pass power and signal cables between racks in multi-bay lineups without consuming rack spaces. Construction is heavy-gauge welded steel with a black powder coat finish, consistent with the seismic-rated approach Middle Atlantic applies across its rack infrastructure products. For government and institutional projects where seismic anchoring is specified, the SRB family provides the documented mounting foundation that inspectors and structural engineers expect.

Key Features

• Early Field Rough-In — Installs before racks and enclosures arrive, so floor anchoring and cable rough-in proceed on the construction schedule rather than the equipment delivery schedule.
• Lower Cable Chase — Provides a protected pathway for passing cables between racks in ganged, multi-bay installations.
• Matched to BGR Series Racks — Sized for one bay of 32-inch deep Middle Atlantic BGR enclosures.
• 24-Inch Height — Raises the rack to a serviceable height while creating usable cable routing volume below.
• Heavy-Gauge Welded Steel — Built for seismic rack installation in facilities governed by structural code requirements.
• Black Powder Coat Finish — Durable finish that matches BGR Series enclosures in equipment rooms.

Typical Applications

• Government space equipment rooms with seismic anchoring requirements
• Broadcast studio rack rooms with multi-bay BGR lineups
• Auditorium and performing arts equipment rooms
• House of worship AV head-end rooms
• Commercial meeting space and campus AV equipment rooms

Frequently Asked Questions

Which racks does the SRB-1-BGR-3224 support?
It is engineered for one bay of Middle Atlantic BGR Series racks at 32 inches deep. Multi-bay versions of the SRB family are available for ganged BGR lineups.

Why install the base before the racks arrive?
Anchoring the base during construction lets electricians and low-voltage contractors complete floor penetrations, conduit, and cable rough-in early, so rack placement at the end of the project is a fast, predictable step.

How does the cable chase function work?
The raised base creates a lower pathway beneath the rack for passing power and signal cables between adjacent bays, keeping inter-rack cabling protected and out of the rack spaces.

Is this base appropriate for seismic-regulated projects?
Yes. The SRB family is Middle Atlantic's seismic riser base line, built from heavy-gauge welded steel for installations where seismic anchoring of equipment racks is specified. Confirm project-specific anchoring details with your structural engineer of record.

Can I combine it with other bases for multiple racks?
For multi-rack rows, Middle Atlantic offers 2-bay and 3-bay SRB models; this 1-bay unit suits single-rack installations or modular layouts.

What warranty and support apply?
The SRB-1-BGR-3224 is covered by Middle Atlantic's manufacturer warranty. For help matching the base to your BGR rack configuration, contact Creation Networks at creationnetworks.net.
