ABSTRACT:
A protective shield for a fire hydrant operating stub is provided which allows direct access to the operating stub by standard authorized tools without requiring the removal of any portion of the shield. The shield includes an inner ring with a peripheral groove which carries a snap ring. A cylindrical outer ring is carried on the snap ring and rotates freely on the snap ring without causing the operating stub to rotate. The outer ring preferably has two recesses formed in its surface to allow placement of authorized tools directly on the operating stub without removing any portion of the shield and the recesses are formed to prevent placement of standard pipe wrenches on the operating stub.
