Tamper-Proof Operating Nut
Tamper-Proof Operating Nut
This simple, yet effective option fights unauthorized operation, theft of parts, and vandal-inflicted damage to the operating and hold-down nuts of dry barrel fire hydrants. A ductile iron cap that spins freely on top of the hydrant bonnet shields the operating mechanism and protects it from would-be vandals. Common tools cannot grip the cap, the operating nut or the specially shaped hold-down nut. Only authorized utility and fire personnel will have the tools needed to operate the hydrant or to remove the cap and hold-down nut if the hydrant ever needs repair.
