Stax, ?

How can you tell which of the lock levers, and hence which doorknob, is the functioning one?

@bpath think he was referring to my dummy comment and the door knob or the op and which was which.

Why are you asking? Yes on is a dummyonly done for a look.

The right one is the right one. (It is the hand of strength and honour.)

People do this on front double doors as well. Always strikes me as silly.

Yes, one is a dummy. It is a nice classic look and you can dramatically fling both open at the same time and feel like a maniacal character in a period piece. I installed salvaged 120 year old doors like this on my second floor laundry closet. I loved the look.

Ever see this headline?

"Home Owner Finds Would Be Burglar Despondent On Front Stoop Trying To Figure Out Which Door To Open"

We still install a lot of dummy knobs, levers & handles but no dummy locks

Doubling a deadbolt w a keylock below is a waste.

That style of keyhole escutcheon and cover that looks kind of like a tassel is the style seen in the Georgian/Federal/Greek Revival periods--at least in the houses of that period where I live.

Particularly in the Georgian and Federal periods, symmetry was extremely important, to the extent that if you had a door on one side of a fireplace, for example, that went into a hall or another room, there would be a door on the other side, that might just open to a blank wall, or if the wall was thick enough, some very shallow shelves.

A number of doors in the buildings I lived had escutcheons and covers mounted on the door with no keyhole underneath, just so that matched the operable lock on the other of the pair of doors. It's not really any more silly or stupid than a lot of things that are done now. And it looks more symmetrical than a keyhole under one only.

I am certain we are all correct but alas, another poster who seems to not be bothered to return and offer anything more.

For real confusion, add another knob and keyhole escutcheon at the opposite edge of each door.

In general, just wondering if people who provide info/comments expect a response if no added info was asked of the poster and it answered their question.

I never go back to postings, unless I wanted to add an additional idea, had asked for more details, or curious on outcome. Life can get in the way and/or poster received sufficient info (oftentimes a personal thank you is received down the road).
