"This is your top choice for inexpensive strong connections with EMT conduit. You can literally do anything. I ordered all 1/2” stuff, but used 1/2 and 3/4 conduit. The 1/2 connections seem to be the same and just come with a plastic spacer. They actually cost like 50 cents more, but it’s worth it for the versatility. I made props for my kid’s marching band." - Ray
