Kit contains items needed for seismic bracing long cable tray runs. Predrilled tabs allow attachment directly to. This checklist focuses on the engineering decisions that matter most when specifying cable trays for high-seismicity projects. In practical terms, the cable tray design. Cable tray runs in seismic zones need more than normal hanger spacing. A coordinated seismic bracing system uses strut channels. Cable trays are systems used for the safe transportation and protection of electrical cables, designed to fit the pathways within buildings and structural installations.
