Ditto. I make it a point to know about weird stuff, and this is the first time seeing or hearing about this fitting. How do you use it?

I have used this type.

It slips into the KO with the pipe and then you just tighten it up, it wedges into the KO and the EMT. They held very tight, went in quick and where great when entering a 4" sq twice on the same corner of the box, (say from the top and side) no threads or locknuts interfering with each other.

A few times I used those in violation of their UL listing. ( ;) ) I removed the chase nipple part and screwed a flex connector into it, thus creating a flex to EMT transition. Now can we please start the debate about how this is wrong and it violates the code and listing, etc? :roll: ;)

I haven't seen those used much. I don't know why, because they seem like a great idea. Very nice when you have to add a pipe to an existing box or put a run of pipe between two existing boxes. When you're working into the last box you don't have to bend and slam the last EMT connector into the box with the "space saver" connector.

I see now. That's sorta the same way that handlebars are held on a bicycle. I bet that fitting messes with your head, though, if it's on the far end when you're trying to push a fish tape through.

We call these two piece connectors. Sometimes used for panel changes

I remember these. They were made by Tomic. We called them "sock-on connectors".
They were a one way fitting. It will not come off. Good thing to remember due to the fact that the pipe goes all of the way into the connector and into the threaded part.
You have to measure it like you would a rigid nipple.
They were good for drilling a hole through a wall and surface mounting a box on. The threads didnt work well at all on a cast box.

That looks useful... is there any other way to put a straight piece of ENT between two existing boxes?

the old way before i known about that connector was one box had to come off the wall to jam the pipe in. those connectors are pretty interesting.

Usually, the length of the thread is shorter than the depth of the connector, so prying the last end in requires very little play, little enough to eke by with centering a slightly-short nipple between the connectors, tightened after installation.

Worst case should only require loosening the box mounting hardware just a bit.
