ABSTRACT:
A locking mechanism for securing the cover of a thin-walled box to the box frame. The locking mechanism includes a two-piece clip bracket having a stationary bracket member and a movable bracket member pivotally mounted to the stationary bracket member. The stationary bracket member is adapted to engage outside and inside surfaces of a wall of the box frame and remain stationary with respect thereto when the stationary bracket member is in an installation position. The movable bracket member is pivotable relative to the stationary bracket member into and out of engagement with the outside surface of the wall when the stationary bracket member is in the installation position. A lock body is adapted to latch to the movable bracket member and engage the cover. A spacer is mounted to the stationary bracket member and adapted to block movement of the movable bracket relative to the stationary bracket member when the movable bracket member is in engagement with the exterior surface of the wall. The spacer is situated so that it is trapped by the cover when the cover is closed and the spacer is blocking movement of the movable bracket member relative to the stationary bracket member.
