Hydra-Shield - Hydrant Security Cap Brochure

Stop vandals and water thieves cold with the remarkable HYDRA-SHIELD® SECURITY CAP … the ONLY hydrant cap that vandals and thieves can’t remove or destroy. The HYDRA-SHIELD® SECURITY CAP is forged from high strength alloy steel, machined, and then heat-treated and quenched to a 58-62 Rockwell “C” hardness. It is virtually impossible to crack or cut and impenetrable to drills. Because there are no opposing faces, no ordinary wrench can grip it. Even if a water thief uses a large pipe wrench, strap wrench or band wrench, only the slip ring will turn.
