Use Cases for Meter Locking Rings

Highfield’s line of meter locking rings are manufactured to American National Standards Institute (ANSI) requirements for electricity meters and provide maximum protection against theft of service and meter tampering for ring type meter enclosures. 

How do meter locking rings work?

Highfield’s series of meter locking rings each have a machined lock housing that accepts Highfield’s line of Utility Security Barrel Locks as well as most barrel locks in the market. 

How are meter locking rings different from ringless meter locks? 

Meter locking rings and ringless meter locks perform the exact same function. The largest difference between meter locking rings and ringless meter locks outside of their shape is how they’re installed. When a meter locking ring is installed on an electric meter box, the electric box cover is installed before the actual meter device, whereas when a ringless meter lock is installed on an electric meter box, the cover is removed prior to the actual meter device installation.

​​With the electric meter box cover installed the installation process is safer for electricians. In the event that an electrician’s hand slips during installation, the cover will prevent contact with live wires.
