摘要 A method and apparatus for locking a water main valve having a handle attached to a valve stem against unauthorized usage includes a method of selecting the apparatus which has a locking cover having a sidewall sized to enclose a portion of a water main valve which has an open bottom and a partially covered top and a first elongated locking arm extending therefrom. The selected apparatus also includes a second elongated locking arm having two ends and having a generally perpendicular yoke extending from one end thereof and having an opening in the other end thereof.
