Around here, conduit comes in ten feet lengths. Five feet long conduit would be an odd size. Those fittings look like standard chainlink fence fittings, not conduit.I’m changing my answer. I’m pretty sure conduit comes in 5’ lengths. So those are two 6’ posts, one buried 12” and the other buried 8” because they hit a root.
I’ll probably change my answer again after another cup of coffee.
