What are rigid couplings?
Rigid couplings are a type of coupling that should only be utilized when shafts are precisely in line. A rigid coupling is only suitable for shafts in close alignment or held in alignment. There are three main types of rigid couplings: sleeve, flanged and clamped.

What is the difference between EMT and rigid conduit?
Rigid is a thick wall conduit that is normally threaded. EMT is a thin wall conduit that is not thick enough to be threaded.
What is rigid conduit used for?
Rigid metallic conduit is most often used in commercial applications but can be a smart choice for straight runs of wire or cable through an attic, garage, basement or crawlspace. It protects against nicks, cuts and punctures to wiring from accidents or chewing animals.
