Abstract: A positioning member for a curb stop box which extends into the ground over an underground valve to hold the passageway through the curb stop box in alignment with the operating member of the underground valve so a tool can be extended down into the stop box passageway for turning the valve on and off. The positioning member comprises a cylindrical sleeve made of a durable rigid plastic material, having securing means such as internal threads to engage external threads on the neck of the valve body. The outer diameter of the cylindrical sleeve corresponds to the inner diameter of the facing portion of the curb stop box passageway when in position over the underground valve.
