Cast J-Box

[mstrlucky74]

Can anyone provide a link to this type of 4" box...thinking Raco make something and I search but the "compression or inside threaded hubs with adapter" is throwing me off. I know what a hubbed box is but INSIDE...??? Want to have my supplier quote it but would like to make sure I'm quoting right box. It's going in slab.


For electrical metallic tubing, ferrous alloy box with compression or inside
threaded hubs with adapter.

Are they asking for a bell box? That's the only thing I can think of with "inside threaded hubs."

I think it has been discussed before that there aren't any EMT to thread adapters.

I read the thread.

So are they saying compression hubs is an option....if that even exists?

While on this subject what type of fitting would be "concrete tight" fittings for emt?

thanks.
