Middle Atlantic BGR Seismic ISO KIT - BGR-ISO-Z4

Middle Atlantic BGR-ISO-Z4 Seismic Isolation Bracket Kit

Overview

The Middle Atlantic BGR-ISO-Z4 is a seismic isolation kit designed to decouple BGR-series rack enclosures from the floor in Zone 4 seismic environments. Where building codes or facility standards require equipment to remain operable after a seismic event, this kit provides the mechanical isolation layer between the rack base and the structural floor — keeping active network, security, and AV equipment protected from shock transmission. At 23 inches wide and just 1 inch tall, the BGR-ISO-Z4 installs flush under the rack without adding meaningful height to the assembly, which matters in equipment rooms with tight overhead clearance.

Compatibility

Designed exclusively for the Middle Atlantic BGR rack series. Verify your BGR enclosure's base footprint matches the 23 in (W) × 4.5 in (D) kit profile before ordering — this kit is specific to the BGR base geometry and is not a universal fit across Middle Atlantic's broader rack enclosure lineup. If you are deploying BGR racks in a seismic zone as part of a larger physical security infrastructure build, confirm local code requirements to determine whether Zone 4 isolation is the correct specification for your site; lower seismic zones may require a different rated kit.

Installation Notes

Shipping weight is 2.8 lbs (1.3 kg), making the kit easy to handle during rack staging. The 1-inch height addition should be accounted for in final rack positioning, particularly where cable management pathways or conduit runs are measured to the rack base. No additional specifications for torque values or required tools are available in current manufacturer documentation — consult the Middle Atlantic installation guide included with the kit or available from the rack accessories product family for fastener requirements specific to your floor type and anchor configuration.
