3 Bay Seismic Riser Base for 31 Inch Deep MRK, VRK Racks
3-bay seismic riser base for 31 in (78.7 cm) deep MRK or VRK racks, featuring a 2450 lbs (1111.3 kg) load capacity
The SRB-3-MRK-3124 is a seismic-rated 3-bay riser base designed specifically for use with 31 in (78.7 cm) deep MRK or VRK series racks. Constructed from heavy-gauge welded steel with a textured black powder coat finish, this component type provides a stable foundation for heavy equipment in high-seismic environments. The unit features a 2450 lbs (1111.3 kg) seismic load capacity and complies with ASCE 7-10 standards. Beyond its structural role, it acts as a lower cable chase to facilitate passing cables between racks. This base allows for field rough-in of structural requirements prior to the arrival of the actual racks and enclosures on-site, streamlining the installation workflow for system integrators.
