    Its a vertical trap, in his mind.

    That possibly is a repair. This is one method for doing a repair between two pipe ends that won't move enough to put a coupling in line.

    Looks like there was an alignment issue and he/she didn't want to cut it back and put in a couple of 45's.

    I have not seen one like that before, but sometimes with long vertical drops, there will be an office to slow down the water as it falls.

    If the home has a metal roof such a device may help adjust the exit point through the roof to avoid piercing an elevated rib and allowing the boot to be installed on a flat surface which would enhance its ability to eliminate water intrusion.

    It appears that the vent would penetrate the roof at the same point without the "whatever". I'm going with apprentice training.

    That was the hook he made to hang all that cable before he decided to wrap it all around the insulation.

    That may be so (or may not). I was not able to discern whether the two vertical pipes are precisely aligned which is what it would take to not change the exit point. My intent was to give the OP an alternate theory to explore when he finds other such devices in the future and not just write them off as a mistake or " I just don't know"

    He ran out of couplings and had to make do with what he had in the truck!
    Been there - done that! Not a big deal if it's a vent line, possible problem for a drain
    since typically a clean-out is required for every aggregate 120 degree or more change of direction.

    Oops, I stand corrected. 135. This was obviously more, technically 4 90's = 360

    Wow! And I thought you guys knew what you were talking about!! It's what is commonly called a "chi break".. when your installing plumbing vents in a hot attic and just cut strait though the chi with a vertical pipe you have to have a "chi break".. saw it on this old house last year.. geez, you guys need to stop doing so many inspections and get some tv time!!

    Looks like a standard trap to me.
    You guys are picky.

    Nope. Turned sideways and it becomes a running trap - which are not allowed ... well, at least not allowed to be installed horizontally, vertically maybe ...
