I realize that in screwing pipes together, one can't make a square and so this is needed:

Last, this guy:

I can tell that its function was to mount a pipe to a wall, but again, I'm sure there's a word for it. (I am seeing "Iron Floor Flange" on searches along with a couple other names, hoping to confirm that's correct).

My daughter told me the lower cross bar was for younger kids so that went away, and that 4 feet was long enough, as she wasn't ever expecting more than a couple people over.

Best Answer

  1. That is a PIPE UNION. It is needed where you are unable to screw the threads together normally. If you look at the structure, you'll be stuck when you try to assemble the top without a union.

  2. That is a PIPE FLANGE. It's not usually used in plumbing per-se but is often used where iron pipes are used for other purposes such as what you are doing.
