Kent, I looked at the photo of that expansion coupling and initially thought, "That'll work". But.... if the conduit was RMC OR IMC all the joints would have been THREADED into couplings, and even if by mistake they were not wrench tight, they would not have pulled apart. Even if strapped too tightly, the roof blocks would probably pull over first. With EMT, contraction pulled apart the weakest link in the chain, a loose slip fitting.
Thanks William.
