Hello,

I had someone ask me what on crosses the large wings at a 45 degree angle with the flow directions are for. Something like the following (if you have a good imagination):

The ones we have are on old cast iron 48"x36" crosses in a pottable

water distribution manifold. The wings extend almost even with the flanges.

I think I remember having heard the reason when I was in school, but don't remember what it was. I could make a guess at why they are needed, but thought I'd just ask you guys.
