About this detail

Suspended equipment weighing up to three hundred pounds hangs from the floor or roof structure above using threaded rod hangers with stiffeners and Mason 30N-23 spring isolators. Lateral seismic restraint is provided by either quarter-inch diameter cable braces or P1000 Unistrut braces installed at a maximum forty-five-degree angle within the equipment footprint. Cable braces connect with Mason type SCB seismic brackets at each end, while Unistrut braces utilize Unistrut P1534A fittings. Three-eighths-inch diameter stiffened rods support equipment under one hundred fifty pounds, and half-inch diameter stiffened rods support units up to three hundred pounds.
