Description

Designed to provide the same cable management facilities as our standard riser bases, but may be used in areas of high seismicity - Zone 4 or Seismic Design Category (SDC) "D". The SRB Series seismic certified riser bases have been rigorously tested to satisfy the following codes and standards: 2007 & 2010 CBC; 2006, 2009 & 2012 IBC; ASCE 7-05 (2005 Edition) & ASCE 7-10 (2010 Edition) and the 2006 & 2009 editions of NFPA 5000 for use in areas of high seismicity - Zone 4 or Seismic Design Category (SDC) "D". These are designed for Mission Critical and/or High-Importance Installations in locations with the highest level of seismicity and top floor or rooftop installations including those within UBC and CBC Essential facilities or IBC, ASCE 7, and NFPA 5000 Seismic Use Group III facilities. For all codes, the Importance factor Ip is 1.5.

With standard 24" height (custom heights available upon request), these riser bases are constructed of substantial 11-gauge steel. Accepts standard angles to support surrounding raised floor tiles. Available for select enclosures, these riser bases require the use of seismic brackets (see below for part #s). Seismic certified riser bases on MRK, VRK, DRK, WMRK and WRK Series
