Middle Atlantic SRB-3-MRK-3624 – 3-Bay Seismic Rib MRK 36"D 24"H

Product Overview

The Middle Atlantic SRB-3-MRK-3624 is a 3-bay seismic rib accessory for MRK series rack systems, configured for 36-inch depth and 24-inch height, designed to provide supplemental structural bracing for MRK rack rows installed in seismic zones or high-vibration environments. Seismic ribs interconnect adjacent rack bays at the top of the frame, distributing lateral forces across the rack row rather than concentrating them at individual anchor points. This accessory is a compliance component for installations in California, Pacific Northwest, and other regions with seismic building code requirements for rack-mounted equipment. It is also used in environments subject to vibration from mechanical systems, HVAC, or adjacent industrial activity.

Product Description

Rack installations in seismic zones require more than standard floor anchoring. Building codes in California and other seismic regions mandate that rack systems be braced to resist lateral forces at both the base and the top of the frame, and the SRB-3-MRK-3624 provides the top-of-frame bracing component for 3-bay MRK rack rows. The seismic rib spans the 3-bay row at the 24-inch height specified, connecting the tops of adjacent racks and distributing lateral seismic loads across the full row rather than relying on individual bay anchors. The 36-inch depth configuration matches the MRK rack footprint for that variant. Heavy-gauge steel construction provides the rigidity necessary to maintain rack alignment under seismic loading, protecting both the equipment and the physical integrity of the installation. This accessory is engineered to integrate with MRK rack infrastructure without requiring modification to the rack frames themselves. Seismic rib installations should be performed following Middle Atlantic's seismic installation guidelines and applicable local building codes. This product is also applicable in non-seismic environments where top-of-rack structural stability is required. Available through Creation Networks at creationnetworks.net.

Key Features

Frequently Asked Questions

Is the SRB-3-MRK-3624 required for all rack installations?

Seismic ribs are required in seismic zones where building codes mandate lateral bracing for rack-mounted equipment. Outside seismic zones, they may still be specified for additional structural stability.

Does this rib replace floor anchoring, or supplement it?

The seismic rib supplements floor anchoring. A compliant seismic installation requires both proper base anchoring and top-of-rack lateral bracing. The SRB-3-MRK-3624 provides the top bracing component.

Is this rib compatible with MRK racks of all heights?

The SRB-3-MRK-3624 is configured for a 24-inch rib height on 36-inch deep MRK racks. Contact Creation Networks for compatibility with specific MRK rack unit heights in your installation.
