The Port Mount Ring Type Hydra-Finder is exactly the same as our Port Mount Hydra-Finder with the exception that it has an extended bracket for extra clearance. The unit can also be totally removed in the event of a fire. The high-visibility Hydra-Finder allows for quick hydrant location, even when hydrants are buried in snow or covered with seasonal vegetation overgrowth. The Port Mount Ring Type Hydra-Finder requires no maintenance and can be left up all year round. The resilient 3/8" diameter, white Matrix fibgerglass Hydra-Finder shaft, which is corrosion free and UV resistant, is attached to a heavy-duty MIL SPEC zinc plated carbon steel spring mount that allows for 360 degree flexibility. The Hydra-Finder is available in multiple colors with different marker lengths and mounting ring sizes.
