Abstract: When hard mounting equipment having a base flange to a curb, a mounting method provides a relatively s-shaped restraint bracket shaped to fit over the top of the curb, and the bottom of the base flange, and having thru holes lined up perpendicularly to the bracket. This bracket is then mounted to the curb, and mounting holes are then drilled through the curb at the bracket thru hole location. The mechanical equipment is then placed on the curb, such that the base flange sits in the restraint bracket, and holes are drilled through the base flange at the location of the restraint bracket thru holes. A restraint bolt is then inserted through the holes and tightened in place.
