Middle Atlantic SRB-2-MRK-4224 2 BAY SEISMIC RIB,MRK,42D,24H

Product Overview

The Middle Atlantic SRB-2-MRK-4224 is a 2-bay seismic rib kit for MRK series racks at 42-inch depth and 24-inch height, providing structural reinforcement for rack installations in seismic zones or where enhanced lateral stability is required. Seismic rib kits are required or recommended in many jurisdictions for rack systems exceeding a specified height and weight threshold. This 2-bay configuration stabilizes pairs of MRK rack bays, tying them together structurally to resist racking and lateral movement. It is an important component for any MRK 42-inch deep rack installation subject to seismic design requirements or building code compliance mandates.

Product Description

The SRB-2-MRK-4224 seismic rib is engineered specifically for the Middle Atlantic MRK rack series at a 42-inch depth with a 24-inch height seismic rib profile. The rib connects pairs of adjacent MRK rack bays at the top and provides the cross-bracing required to meet seismic performance requirements in applicable building codes including IBC and CBC seismic design categories. The 2-bay configuration addresses the most common gang row pair scenario, where two MRK bays share a seismic rib across their combined top span. Steel construction with Middle Atlantic's standard black powder coat finish ensures durability and consistency with the MRK rack system appearance. Installation follows Middle Atlantic's seismic installation guide and may require floor anchoring in addition to the seismic rib for full code compliance depending on the authority having jurisdiction (AHJ). The 42-inch depth specification matches MRK-42 series racks, and the 24-inch height designates the rib profile height above the rack top. Proper seismic bracing protects both equipment and personnel in the event of a seismic event and reduces liability for integrators and facilities managers.

Frequently Asked Questions

Is the SRB-2-MRK-4224 required in all jurisdictions?

Seismic bracing requirements vary by jurisdiction and seismic design category. Consult the authority having jurisdiction (AHJ) and the applicable building code to determine if seismic ribs are required for your installation.

Does the SRB-2-MRK-4224 alone satisfy seismic compliance?

The seismic rib is one component of a complete seismic compliance solution. Floor anchoring and other measures specified in Middle Atlantic's seismic installation guide may also be required. Contact Creation Networks at https://creationnetworks.net for compliance documentation.

What is the difference between SRB-2-MRK-4224 and SRB-3-MRK-3124?

The SRB-2-MRK-4224 is for 2-bay configurations at 42-inch depth, while the SRB-3-MRK-3124 is for 3-bay configurations at 31-inch depth. The two products are not interchangeable.
