1 Bay Seismic Riser Base for 42 Inch Deep WMRK Racks
Seismic riser base for 42 inch deep WMRK racks, 1000 lbs capacity, and 1-bay configuration
The SRB-1-WMRK-4224 is a single-bay seismic riser base designed specifically for use with 42 inch (106.7 cm) deep WMRK series racks. Built from heavy-gauge welded steel with a textured black powder coat finish, this base provides a stable foundation for seismic-rated installations. It is engineered to allow for field rough-in work to be completed before the actual racks and enclosures arrive on site. Additionally, the base serves as a lower cable chase, providing a dedicated pathway for passing cables between racks. This unit is TAA compliant and carries OSHPD 96-01027 and ASCE 7-10 certification. It supports a seismic load capacity and weight capacity of 1000 lbs (453.6 kg). With a height of 24 in (61 cm) and a width of 23.94 in (60.8 cm), it is a critical component for integrating seismic-rated enclosures into high-density rack systems.
