Security Hydrants

  • Uses conventional padlocks
  • Mounts on 1-1/2" pentagon
    (AWWA standard)

The HydrantLok™ is designed to
deter access to water systems
through fire hydrants. With the lock
in place, the hydrant’s operating
nut cannot be turned in either
direction. No special tools are
required for installation, and quick
access to the integral pentagon
operating nut is accomplished as
quickly as removing the padlock.
Lock is made of ductile iron with a
durable powder-coated red finish.
The hydrant lock’s unique
hasp-type locking device is
designed to accept most padlocks
with shackles up to 5/16" in
diameter, so you have the option of selecting the style of lock that best meets your requirements.
