Looks like a atkor threadless rigid compression connector

I agree just a threadless RMC connector, looks like aluminum conduit.

Looks like maybe the threads are still on RMC?

Could be that or just a shadow from the photo. I've seen many a fitting like this with the threads still in place.

Agreed , I too have seen it before. Wonder why it would be called a threadless fitting if you left the threads on? Seems as though fitting would not be listed for this usage as may allow water in? Then , maybe it’s a shadow.

It's called a threadless fitting, because it can be used without adding threads to a cut end of the conduit.
This doesn't necessarily mean you have to remove threads you aren't using. Some "threadless" fittings can be installed with or without threads on the conduit end, depending on the details of the product listing and instructions. For instance, I've seen weatherheads that are "thread agnostic", and can work with or without threads on the end where it is installed.
Most compression or setscrew fittings for RMC that I've seen, are not permitted to be used on threadded ends, and require a straight outer wall to work.

It's an Erickson fitting for GRC.

It's threaded into the hub on a box so I don't think that it's a 3-piece Erickson fitting.

They also manufacture them (Erickson fittings) w/ male ends on one side. Not just coupling fittings.

You may be right but I've never seen what you've described do you have a link to one? Around here Erickson is the brand name of a 3 piece coupling.

I’ll take your word I never really care about brands when I order stuff I would just say threadless rigid male connector and get what I get

A Myers hub is not a threadless rigid male connector. It has male threads on the end that enters the enclosure, and female threads on the exterior end. I don't think Myers hub is what Post #13 meant by Erickson male connector. I would expect that an Erickson male connector would allow you to lock it in to the enclosure on one end, and thread it onto the conduit on the other end, without rotating the conduit.
Similarly, an Erickson fitting isn't threadless either. Erickson usually refers to the Erickson coupling, or 3-piece coupling, that allows you to connect two threaded conduits without rotating them as you assemble them. The pieces of the coupling get rotated instead. The analogous plumbing term is union.

I know and the only difference between an Erickson coupling and a threadless is an Erikson is explosion proof

It could also be a swivel connector which allows you to thread the connector into the hub of the box and then thread the other end of the connector onto the RMC without having to turn the conduit.

Looks like a thread less RMC connector to me. It's non an Erickson or a Meyers as far as I can see
