I can't remember off the top of my head, but I think I have 3/16" and 1/4" holes in this spray bar. Instead of just capping the end like I did, I would make both ends look the same and then cap one. that way it hangs itself on the rim instead of having to suspend the one end with a zip tie.
Good to know, thanks. What's a good diameter size for the actual spraybar?
