Lately I came across some large elbows about 3” and I seen holes drilled for 1/2” EMT. I can’t think of how this could be code compliant but I have been wrong before.

Help on this one appreciated

When you say “elbow” are you talking about a conduit short body elbow?

They have a 1/2” hole drilled into them to run another piece of conduit?

If described accurately, it’s definitely not code compliant

Ok I'll bite. What exactly is the code violation?
110.12 because it’s ugly 😎
110.2 Approval, Doubt my AHJ would approve it.
110.3(B) doubt the manufacture would approve it
230.7 if the elbow is for a Service
314.28 wire bending space, conductors #4 and larger, although that would be hard being the OP had a 1/2” in 3” as an example.
You have also introduced a threaded entry/lock ring/bushing in the elbow that is going to interfere with the other pulling dimensions/abrasion. Also depends on where this extra EMT connector is installed.
Is the elbow PVC with the EMT addition, now add a bond bushing in there.

I’m sure there are other articles that could be cited depending on the full details. But damn, it is hard to cite something solid on it. Thanks for putting me on the spot 😁

Yeah I do believe it is pretty hack and cringe....
That said I am very cautious about people/an inspector failing something just because he "doesn't like it". I'm still not clear if we are talking about a 90° elbow or an lb. Seems the word elbow is used, but it's hard to even imagine how that would work. I guess there would have to be a box or cabinet right at the end of the elbow, and the fitting quite close to the termination of the conduit run. If it's an lb I don't really have much of a problem with that honestly, if there wasn't an easy better way to do it.

Okay I missed that the op links to a picture of an LL or LR (whichever one it is, still haven't nailed that down after 20 years of doing this crap).
If you hold the LL or LR like a pistol, the opening towards you and the hand it’s in will let you know which you have.

I used to hate it, boss would say bring (2) LLs and an LR and I’d always screw it up

Stand it up like an upper-case L so you can see the cover.

Whichever way the lower leg points is the type of Condulet.
