ABSTRACT:
Locks securely close a commercial electric power meter box at the front of the meter box where it is visible by a meter reader. One version of the lock readily indicates unauthorized entry into the meter box by extending the seal to the front of the box. Another version of the lock requires a special tool to remove the lock in addition to extending the seal to the front of the box. Yet another version of the lock is equipped with a fully enclosed and protected cylinder lock, which cannot be opened without a special tool and a key even if the seal is broken. All of the locks can be easily installed on existing commercial meter box installations.
