Abstract
A lockable ring assembly for securing an electric meter in a meter box comprises a split ring having a U-shaped cross section, a keeper stud mounted to the split ring on one side of the joint thereof, and a lock housing mounted to the split ring on the other side of the joint thereof, the lock housing defining a keeper stud opening for receiving the keeper stud and a lock receiving opening for removably receiving a barrel lock. The keeper stud and lock receiving openings intersect, and the keeper stud has a notch providing clearance for inserting the barrel lock in the lock receiving opening, whereby the barrel lock engages the keeper stud to hold the ring closed. The split ring is preferably formed in two semi-circular ring parts joined by a hinge for articulated opening and closing action during installation and removal.
