Have any of you ever seen this? And if so, can you give me an explanation?
This is a typical box that would be used to trim around a wall opening or electrical box for vinyl siding.
Whats really weird is that the base plate is put on backwards. If you peak inside the holes, you will see the bare sheeting as well as some electrical wires.
