Friday was another great day; we were listed by Seismic Source International after flying through their QA/QC requirements. Our huge professional engineering staff with registrations in 50 states, OSHPD approvals, proven seismic restraints, snubber cable assemblies, etc., etc., have kept us busy keeping up with your demand for the highest industry’s standards. As a direct result of the San Fernando Earthquake in 1971, the San Francisco ASHRAE chapter honored Norm Mason in 1972 by asking him to conduct a seminar on the topic of “Protecting Isolated Machinery in Seismic Zones” At that lecture, passive, highly cushioned seismic snubbers were introduced for the first time. We went on to study force transmission based on response spectra curves with the assistance of Dr. Wilfred Iwan, Department of Earthquake Engineering at Caltech/Pasadena. Fortunately, by the 1994 Northridge Earthquake, many of our system were in place and none failed in sharp contrast with our competitors’ systems. Seismic Damage Bulletin (SD-100) |

As Manufacturers, this would be self-serving when the whole industry is struggling to move forward. All of our Representatives as well as the Los Angeles and New York Offices are here to help |
