KingLock reviews

Company Information

The KingLock takes fire hydrant security to a new level. The padlock- secured housing deters unauthorized access to the hydrant’s operating nut.



With the lock in place, the outer shell rotates freely in either direction around an inner operating nut extension that is secured to the hydrant’s operating nut, thereby preventing the hydrant operating nut from being turned.



Fast access to the operating nut simply requires removing the padlock and flipping the top cover back 180�. No parts to remove except for the padlock!



KingLocks have an integral instrument cavity in the head, into which an optional alarm package can be installed at any time in the field.



The alarm package includes a high frequency 120dB electronic alarm that will sound within 33 seconds if an alarm code is not entered on a membrane protected keypad after the KingLock’s hinged cover is tilted past a preset position.



The 9-volt battery has an 18 month life expectancy under normal use.
