The Dome Lock (Patented) is designed to provide a cost effective means to secure your hydrant system. It attaches directly to the hydrant operating nut and the free-spinning dome prevents access to the hydrant operating nut. Due to the design of the Dome Lock, it can be used on almost all hydrant models. The special security wrench fits the security plug in the dome and is used in the installation and removal of the dome.

After the dome is removed, a 1.5″ pentagon operating nut on the centerpost is used to open and close the hydrant. The fire department will still use their standard hydrant wrench for this. When you need security, but your budget is tight, remember the Dome Lock!
