When conducting a vulnerability assessment, infiltration of a municipal water supply through an unsecured fire hydrant should be a primary concern.
The Mueller Hydrant Defender Device provides security to the hydrant nozzles at two levels. First, the 14 gauge (.075``) 304 stainless steel straps prevent unauthorized access to all but the most determined individuals. Second, unlike most other security devices, evidence of tampering will be clearly visible.
The stainless steel barrel lock features a key, or keys, that are uniquely coded for the purchaser and strictly controlled by the manufacturer. When the device is securely locked, the hydrant nozzles and the operating nut can only be accessed by completely cutting through the heavy straps or barrel lock. Damage to the straps or lock will be clearly evident, even from a distance, and the water authority can investigate the problem immediately.
