LB both sides of wall?

[PoorOwner]

Running a new feed wires.. it will go downward from surface mount main panel bottom, where it will go into LB, thru a hole in the exterior wall, and a second LB on the inside pointing upwards.

I have trouble thinking about how I can tighten this stuff together. rain tight EMT fittings on the exterior LB and set screw conn. on the interior LB. Both threaded metal LBs.

Do I experiment with the rotation of the set screw side and thread the LB on from the outside and hope it stops at the right orientation? Or just give up and put a box on the inside? So much easier with a lock nut on one side.. or using PVC, not really keen on PVC idea because I need a bit of offset on the outside.

Thanks

Compression connector threaded into interior LB. Orient interior LB however you want, and tighten the compression fitting down.

Cut a piece of Rigid threaded conduit to fit.

You will be able to tighten them perfectly aligned.
