ABSTRACT:
A multilobe bonnet is provided for the upper end of a fire hydrant with the multiple lobes thereof projecting upwardly from the bonnet at points spaced about and radially outwardly from the conventional pentagonal upper terminal end of the hydrant valve control rod, the upper terminal end projecting above the upper surfaces of the bonnet disposed centrally between the upwardly projecting lobes disposed thereabout. In addition, the side outlet closure caps of the hydrant are formed in a similar manner with the lobes on the bonnet preventing the engagement of a convention wrench with the valve control rod upper terminal end and the lobes on the closure caps similarly preventing engagement of conventional wrenches with the central pentagonal projections on the caps.
