Force-resistant locking devices for electric meter boxes with hinged cove or the like, comprise a stud member mounted to a wall of the box and a flange member received on the stud member, the flange member including a flange overlying a marginal portion of the cover to keep it closed. The flange and stud members together define an opening receiving and fully enclosing a utility lock for securing the flange and stud members together. In one embodiment, the flange member is an angle iron with rectangular metal stock welded to one leg, and the stud is cylindrical and received in an opening through the flange member. The lock-receiving opening intersects the stud-receiving opening and the shear strength of the utility lock holds the locking device together. In another embodiment, the flange member is a section of channel iron and receives a rectangular stud, the lock-receiving opening deployed to utilize the shear strength of the lock. In a further embodiment, the flange member includes a polygonal post engagingly received in the stud member, and the lock-receiving opening is axially aligned with the post.
A locking device adapted for combination with electric meter boxes or the like of the type having a bottom, a back wall, side walls, a front wall and a cover hingedly or otherwise attached to the back wall and pivotal to a closed position, the locking device comprising:

A locking device adapted for combination with electric meter boxes or the like of the type having a bottom, a back wall, side walls and a front wall and a cover hingedly or otherwise attached to the back wall and pivotal to a closed position, the locking device comprising a stud member mounted to one of the walls other than the back wall of the electric meter box and extending perpendicularly outwardly therefrom, the stud member comprising a rectangular base positioned adjacent the wall of the electric meter box and a cylindrical stud extending outwardly therefrom, the stud defining a portion of a lock-receiving opening, and a flange member defining an opening in which the stud is received, whereby the flange member is removably received on the stud member in an interengaging relationship, the flange member including a flange which overlaps a marginal portion of the cover adjacent one of its free edges, the flange member defining the remaining portion of the lock-receiving opening which aligns with the portion of the lock-receiving opening defined by the stud member and the flange member are assembled together, the lock-receiving opening defined by the flange member and stud member being generally perpendicular to the closed cover and intersecting the stud-receiving opening defined in the flange member, the respective portions of the lock-receiving opening together receiving and protectively enclosing a utility lock of the type having a head, shank and locking balls which are expansible from the shank to engage a shoulder of the lock-receiving opening and thereby retain the utility lock in the lock-receiving opening, whereby the shear strength of the utility lock in the lock-receiving opening prevents separation of the flange member and stud member and thereby secures the stud member and flange member together to maintain the electric meter box in its closed condition.
