Chatsworth Products, Inc. (CPI) Seismic Protection Systems reduce the risk of equipment damage by stiffening, bracing and stabilizing racks and rack-mounted equipment to comply structural recommendations. When planning installations in seismically active regions, CPI helps reduce the approval cycle by obtaining Office of Statewide Health Planning and Development (OSHPD) Pre-Approval (OPA) numbers for several IT infrastructure products.
