Do they make meter banks that hold 3 meters?

I have a house that was turned into a 3 unit apartment.

I was planning on using a 3 meter disconnect bank. Then going with main lug sub panels. but... .

The dryers and ranges are all old 3 wire. If I run sub fed panels I will need to upgrade these old wires. I really don't want to do that.

So I need just regular meters. I know the electric company has dual meter cans for 1 drop but I havent seen 3 meter, cans for 1 drop. .. Do they make something like this?
