suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, cor-
roded, deformed or non-load rated component could significantly reduce the strength of the installation,
placement, or array. Any such condition severely reduces the safety of the installation and should be
immediately corrected. Use only hardware which is rated for the loading conditions of the installation
