I don’t think those are thread protectors. I think those are couplings used to hold 10’ sticks together during transport
We call them thread protectors and the 21'ers have them on one end too.

I concur. I always worry about one coming off driving down the highway and bouncing off the road and busting someone’s windshield.

That’s why I haven’t bought a piece of black iron or galvy in 20 yrs. I’m scared of the thread protectors falling off.

It’s all copper now breh. I braze or flare. The younger kids use the gas press fittings.
