ABSTRACT:
A hydrant protector for preventing unauthorized use of the hydrant includes an internally threaded tubular shleld around the valve stem. To prevent a collection of trash in the shield and to provide more security for the hydrant a threaded plug fits completely into the shield and against the end of the valve stem and has, in the flat exterior end, a pentagonal keyway of deep grooves. A wrench having a pentagonal tubular socket to fit the keyway will also fit the valve stem.
