    The ones with set-screws can be used without connectors.

    Pulling elbows are available for 2" from Gordon Electric

    Additional detail

    Both elbows are near the very ends of the run. I could replace them easily. Thoughts on doing that? Why - why not?

    Well - I was asking the question after the install. And yes, the wires got a little scuffed. That is three #6 and a #8 in 3/4 (not 1"). Conduit fill for the straight run is OK. The Elbows are not labeled and it is tight. Will it pass? Who knows.

    Also never seen any wire size information on a short body fitting.
    I've seen the ones with a removable cover in 1" at the box store.

    I haven't either, but I haven't looked either.

Wires got pretty scuffed in the process but it tested okay and didn't fault. Looked at the elbow markings afterward and realized why I had such a tough time.

    Moral of the story is that when using these things you've got to watch out because conduit fill tables will tell you that you can run a 3-wire circuit plus ground with a wire size larger than the pulling elbow allows for that size raceway. Doesn't happen with normal LB fittings so far as I've noticed.

    Naturally they will be stranded but the insulation type makes all the difference. THHN is about the easiest to pull.

    In a real LB, that combination goes in 3/4 just fine, but the short fitting like pictured wouldn't take #6 very easily without risk of damaging it trying to get it in there. Even 3/4 and 1/2 inch with 12 and 14's installed doesn't work so well with those short bodies if near max conduit fill.

    An LB would be slightly easier to pull through than a pulling elbow.

    Similar question for 3/4". In this case I have 3 #6 and 1 #8. Can I take that around an elbow?

    . Small stranded wires and short distance only are doable with those. Definitely not Max conduit fill.

    Thank you everyone for the responses. Also, I noticed that the 1" elbows do not have set screws (oversight when purchased). I cannot find anything on line. Are those still acceptable for EGC bonding?
    Made up wrench tite, yes.

    Reply and another question

    Edit: Tom, I guess great minds think alike!

    I too would use a J-box (for the reasons stated).
