Middle Atlantic BGR-Z4 Seismic Floor Anchor Brackets

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND BGR-Z4 is a set of seismic floor anchor brackets designed to secure equipment racks to the floor in installations where seismic restraint is required. These brackets provide a fixed anchor point between the rack base and the floor structure, limiting rack movement during seismic events or vibration-prone conditions. Licensed AV integrators, data center technicians, and electrical contractors install these brackets as part of a compliant rack anchoring system. They are sold as a single unit and classified as a rackmount accessory.

Seismic floor anchor brackets like the BGR-Z4 are used in commercial and institutional environments where local building codes or data center standards require rack stabilization. Typical applications include server rooms, network closets, broadcast facilities, and any installation where freestanding equipment racks must be anchored to a concrete slab or raised floor structure to meet seismic zone requirements.

Installation Notes

Installation is typically performed by a licensed AV integrator, electrical contractor, or data center technician. De-energize all rack-mounted equipment before beginning anchor installation.
