do they make 5/8" extension ring for an outlet box?

They make a ring that just slips inside the box for things like this. You end up using longer screws and the ring is a sleeve that covers the gap between the surface and the box.

You are required to have the box extend out.

Thanks John, that was what I was poorly trying to describe.

Thanks for the link. Thats exactly what I'm looking for. I see they are made of plastic. I wonder if I can still use them with metal boxes. This is in a condo where everything is BX. Would Lowes or HD have these box extenders?.

They are available in most hardware stores and surely in Lowes and Home Depot.

They're made in metal too, but you're better off with plastic, no concern about shorting out. Regardless of what the extenders are made of, you will have to run equipment grounding conductors from the box to the receptacle.

I did find Raco metal extenders at HD. I wanted metal because this is a condo bldg I'm working in and code calls for bx and metal boxes, so I just wanted to play it safe. They came with 2 long screws which is nice. Thanks for everyones help.
