Redesigning the Fire Hydrant

The Spartan by Sigelock improves upon the centuries-old design of the fire hydrant.  Virtually indestructible, the Spartan is made of stainless steel and ductile iron, and covered in a powder coating that prevents corrosion even in the face of storms and salty water. Its internal drainage system sports an efficiency that prevents damage  from freezing water. And it can be opened within seconds using a special wrench, which discourages water theft and vandalism.
