1 Bay Seismic Riser Base for 48 Inch Deep MRK, VRK Racks
Seismic rated 1-bay riser base for 48 in depth MRK or VRK series racks with 1000 lbs capacity
The SRB-1-MRK-4824 is a seismic rated 1-bay riser base designed specifically for use with 48 in (121.9 cm) deep MRK or VRK series racks. Constructed from heavy-gauge welded steel with a textured black powder coat finish, this component serves as a critical foundation for seismic-prone installations. This riser base allows installers to perform field rough-in of infrastructure prior to the arrival of the actual racks and enclosures. Once installed, it functions as a lower cable chase, providing a dedicated pathway for passing cabling between adjacent racks. The unit is engineered to handle a seismic load capacity and weight capacity of 1000 lbs (453.6 kg). It is TAA compliant and meets ASCE 7-10 standards, and carries OSHPD Number 96-01027.
