Tamper-Resistant Hold-Down Nut
Tamper-Resistant Hold-Down Nut
The Mueller® Tamper-Resistant Hold-Down Nut is specially designed to make Mueller Centurion® and Improved fire hydrants more resistant to tampering. It replaces the existing hold-down nut (and weather cap on hydrants dated 1987 and earlier) and surrounds the operating nut, helping prevent unauthorized operation of the hydrant. The special operating wrench for use with this option may also be used with other hydrants.
