This rooftop equipment curb assembly rests on a 12-gauge bottom curb supported by 12-gauge C-sections at each isolator location. A wood nailer provides a structural base beneath a continuous neoprene weatherseal. Vibrex RMU-EQ-SH vibration isolators with leveling bolts sit between the curb and the mechanical unit. Fourteen-gauge seismic straps secure the unit using number twelve sheet metal screws. Gasketing provides a tight seal at the interface with the rooftop unit.
