Overview of a cable tray seismic bracing load path from tray rail to structure. This guide serves EPC engineers, MEP contractors, procurement teams, and site inspectors working on industrial plants, data centers, metro and tunnel projects, and commercial buildings. Why is seismic bracing important? International Building Code. Up to 50% faster to install, the seismic bracing cable kit system is designed to brace non-structural equipment and distribution systems to help minimize damage in a seismic event. A standard trapeze support carries gravity load; it does not reliably stop lateral sway, longitudinal movement, anchor pullout, or cable spill during ground motion. A coordinated seismic bracing system uses strut channels. Cablofil Wiremesh Cable Tray concept based upon performance, safety and economy; three qualities which make Cablofil Wiremesh Cable Tray system preferred by installers. Cablofil adapts to the most complex configurations, and its structure gives maximum strength for minimum weight. The bracing system was designed to meet building code requirements in addition to the owner's design criteria.
