Assuming you do mean the ring and not the lock, I too use a 4 inch grinder.
The ring is "C" shaped and a little tricky getting the back side. I grind it
down, but not through, then use a medium screw driver to chisel it apart. If
you cut to deep, you can damage the metal band that holds the glass to the
meter or break the glass. Utility companies have a lock breaker for these,
but it doesn't always work

Any idea how to remove this ring?
