1 Bay Seismic Riser Base for 42 Inch Deep MRK, VRK Racks
Seismic rated 1-bay riser base for 42 in deep MRK or VRK racks, 1000 lbs capacity, OSHPD 96-01027 listed
The SRB-1-MRK-4224 is a seismic-rated riser base designed specifically for 42 in (106.7 cm) deep MRK or VRK series racks. This 1-bay component is constructed from heavy-gauge welded steel with a textured black powder coat finish to ensure durability in mission-critical environments. It is engineered to act as a lower cable chase, providing a dedicated path for passing cabling between racks. This riser base is particularly useful for field rough-in, allowing installers to establish structural footprints prior to the arrival of the actual racks and enclosures. With a seismic load capacity of 1000 lbs (453.6 kg), it provides a stable, certified foundation for heavy equipment deployments. This unit is TAA compliant and carries OSHPD number 96-01027 and ASCE 7-10 compliance.
