Operating nut for fire hydrant

摘要

An operating nut construction for a fire hydrant including a body member having a lower tapped portion for threadably receiving a fire hydrant valve rod, a sleeve rotatably mounted on the body member against axial movement, a cap rotatably mounted on the body member against axial movement, a narrow gap between the sleeve and the cap, and a plurality of shallow depressions in the body member aligned with the gap for reception of a specialized wrench having narrow shoulders thereon to turn the body member. The rotation of the sleeve or the cap or both will not turn the body member because they are rotatably mounted thereon.
