AFAIK you cna't go horizontal with a ring, but I have limited experience with it. My friend bought a house that had an old Nutone system in it.  We yanked it out and then he didn't have a doorbell.   We removed the Nutone doorbell, he had a piece of wood cut and routered to look nice and then screwed to the recessed rough in rack of the Nutone doorbell.

I thought it was going to look like a turd on a stick...It actually looks nice...But it was all the carpenter...the carpenter took some time and put some pretty cool styling into it with his router.
