Inner-Tite Corp.®, manufacturers of security devices for utilities, announces the granting of a U.S. Patent for the self retained barrel lock. The patent applies to the design which allows the barrel lock to be installed into the locking device without the need for a key. No special modifications are needed to the barrel lock thereby allowing for seamless integration with most plunger style barrel lock systems.

With this patented preload feature, the utility company does not require a key to install, resulting in improved key control and better system security. This design is not limited to one locking device, but can be applied to many current and future locking device designs.

The Rhino Ring is a heavy-duty hinged meter locking ring designed to secure ring style meter sockets for the long term. In addition to the patented Preload feature, the Rhino Ring features heavy gauge carbon steel construction, a unique recessed hinge for easy installation, case hardened construction to resist cutting tools and weather resistant cadmium and yellow chromate plating.
