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.

DETAILED DESCRIPTION Briefly, the present invention provides new and improved locks for commercial electrical power meter boxes having closure tabs in the bottom wall of the box.
The locks have a socket member adapted to fit over the closure tabs of the meter box.
A sleeve is connected to the socket member for extending the wire seal to the front of the meter box.
The outer end of the sleeve has a flange connected to it.
The flange has a series of apertures therethrough which surround the sleeve.
A lock rod member is insertable through the sleeve and into the socket member where the rod passes through the closure tabs of the box for locking same.
A cap having a series of apertures closes the outer end of the sleeve.
The cap apertures are aligned with the apertures in the flange to permit a wire seal to be inserted therethrough.
Locks according to the present invention are easily and quickly installable on commercial meter enclosure boxes with no requirement for replacement or retrofitting of the thousands of existing meter boxes.
