I was on the roof of one of our schools and noticed something I have never seen. The hose bib coming out of the roof about 3 feet the stand pipe has some kind of cast stiffener around it. Not sure if that is what it is or not. It looks like a round ladder with a bolt in the top and bottom rungs to hold it in the middle of the pipe. Just wantted to know what it is for? Sorry I do not have any pics.
No announcement yet.
What is it
