Reno I am guessing you are talking about the thread to thread connector with lock nuts on both ends. These are EMT to thread.
It does make a lot cleaner installation than an offset, less places for spider webs. wink
When used with a KO and a lock nut it is easy to insure it is tight when properly aligned. When you have a threaded hub like a Bell box it gets tougher.
