Hydra-Shield - Hydrant Dome Lock Brochure

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.
