Default Ring Type VS. Ringless

Would someone please explain the difference between "ring type" and "ringless" meter bases, and the pros/cons of each. Thank you.

The ring type meter socket consists of a cover that usually screws onto the box. The meter then plugs into the socket, and a metal band (called the sealing ring) is snapped around the meter and then depending on the type of sealing ring, a screw is tightened (some just snap together) then a meter seal goes through the screw or snap hook to "lock the meter. It can be equipped with a high security lock as well.

Here is a photo. Notice the flange that goes around the rim of the opening where the meter plugs into. The cover is put on first, then the meter is plugged in.

Another, older style model:


Big meter stacks (like you'd see on an apartment, are generally also ringed type) It allows the POCO to mess with one meter at a time, instead of taking a big cover off a big mess of meters. It is also common to see ringed meter sockets on older meters.

The ringless type is generally more common for single meter sockets. The meter is plugged in, then the cover is put on and then a latch is locked on the box and a sealing ring is put on. Some times it is spec'ed by the POCO.

A pic of a ringless meter socket:


Notice the latch at the bottom.
