Daniel Cannon of Allegion sent me these Wordless Wednesday photos of the back door of a restaurant. What say you?

I’m guessing by the scrapes on the frame this is some make shift maverick bar that was used. If not still in use at night.
I’m guessing it’s still in use and is leaning up against the wall next to the door!

And the sans-thumbturn dead bolt. Can that be locked on the exterior -cause it can’t be unlocked from the interior. And I don’t recognize the dot below that.
OK, I must be missing something. I can’t figure out how that thing is supposed to work.
I think Sheldon has a good theory…check out his comment.

Looks like a home made version of Exit Security’s “hook-on series”, see link http://www.exitsecurity.com/

I think you’re right!

Is the other bar (the one leaning against the wall) longer and made to fit on top of the door mounted bar? I’m guessing it is angled in such a way to wedge between the inside rabbets and behind the stop. It looks like the two long pins hold it in place at night???
The long bolts sticking down through the bar on the door are removed.
The bar leaning against the wall is placed on top of the bar on the door, extending to the left to engage the stop.
The bolts are dropped through both bars, securing the upper bar in place.
Voila! The exit device is defeated.
That’s what I thought!

But if the bar on the wall is placed on top of the one attached to the door, how does it engage the stop? The bar on the door is between the stops. If you place the other one on top, it would have to fit between the stops as well. It somehow must be offset to engage the stop(s).
We may have a first here: the pic requires a follow-up visit with the owner demonstrating how this works.
Judging from the marks on the frame, I think the second bar goes against the face of the frame and attaches to the bar on the door.

Found this interesting picture while looking for an example::

If you enlarge the picture you will see the bar on the door is mounted on standoffs that move it out clear of the frame allowing the longer bar to mount on top.
Clever…Too clever!
