I came across this vent (or with I believe is a vent) on a 2001 build yesterday. I have not seen these before, anyone have a link or seen before?
I figure it is for a bath exhaust. I was trying to locate on the internet.
Mike Larson is a good one for finding links to, as well as others.
It’s a trim out box for future lighting put on during the siding job.
It’s next to a patio door I bet. 
Here you go.

Looks alien. I hope you didn’t touch it!
I disagree as it clearly has a peace symbol embedded in it .
You still trippin Bob? :mrgreen:
Nice work Mike. Never seen one.
Mike I am always amazed at how you know all these things. I had to look all over google to identify a gold plate in the floor. It was an outlet…
