All the duct is being pulled from this house and replaced after water flooded it. I think they are about to get an upgrade too!
Keep in mind no runs came off before this fitting.
That was actually installed somewhere?
The only reason I can think of for building something like that would be to take pictures of it for a textbook, as example of how NOT to make an offset...
If more government is the answer, then it's a really stupid question.
