Thanks. Have 2 questions: If you use them say on 3/8" Greenfield does these decrease the # of wires allowed and it appears to be made of die cast material that is some what fragile. Does anyone manufacture them.in steel. As a rule I rather pay more for steel fittings then die cast.

Yes for 3/8" FMC there is a reduction in the number of conductors when the connector goes inside of the raceway. See Table 348.22.

Those are both 3/8" FMC connectors, not MC connectors. The last one:
Screw-In Connector 3/8″, Die Cast Zinc
Use Bridgeport screw-in connectors to make fast, reliable connections between flexible metal conduit (FMC) and an electrical box or enclosure knockout.

Looks like I got lucky. Those things work great when fishing MC down the wall and using them on deeper device boxes.

I think they need to get listed for MC. They work great and it's impossible for the conductors to short on the sharp edges of the metal sheath. Thanks for clarifying the listing.Those are both 3/8" FMC connectors, not MC connectors. The last one:

If it was not listed and you did not have approval from the AHJ would never want the possible liability issue down the road. Had artist that wanted me to install home made luminares but told them they would have to have them spend a lot of money to have them inspected , hopefully meggered with at least 500 volts and sign a form from my lawyer releasing me from any & all liability issues. One saved money by having the carpenter run wire, hang boxes and wire in thier hone made luminares.

Right because we all know GC's, Handymen, and Plumbers don't have to follow the NEC.
PS and don't need no stinking inspections.

LOL…
I read that in my head as “McConnector”, as in a connector you might order at McDonalds….
I must be hungry.

Whether rated for MC or not, I used one of these when I had to re-hang a wall-pack light. You can see why the light fell by comparing the original hardware to what I used.
In the last pic, you can see the red bushing behind the old tape. There was zero slack in the cable. The black wire was broken, so I connected both drivers to the red wire.

I really like this type of old work MC connector when I am fishing in MC to a box, you can pull the MC into the box, snap on the connector and then push the MC back into the wall until the connector snaps into place
