4x4 recessed junction box with 1-1/4" conduit

[Shujinko]

What is the smallest depth size for a 4"x4" wall recessed junction box in order to fit an 1-1/4" conduit on it? How about the depth for an 1-1/2" conduit? It's just to run AV and data cables in it, no wiring devices installed in the j-box just cables passing through.

Garvin makes 5" square deep boxes that have 1 1/4 KOs and mud rings to match.

Well, you have to fit the fitting and locknut, plus the wall-surface thickness.

I have found 4" deep ones:

Wow!

Why do you need a box? Why not just end the conduit near where you'll have a low-voltage ring and cover?

And how many boxes have each of us seen that where so stuffed with cat 6 cables they couldn’t put the cover on, looked like a blue bubble

This is good info but I am asking for the smallest depth not the largest.

 

[LarryFine]

I don't think there's a legal minimum. As I said above, you have to fit the fitting and wall.

Garvin also makes a 4in deep 4sq box with no knockouts. I like Garvin and their wierd stuff.

For 1.25" KO a 2 1/8" deep standard box will work if you can use a 4 11/16" box instead of a 4".

Sign of PPP.

4" sq box that is 2 1/8" deep... You will have to knock out to 1 1/4"....

I think I would only do this if I were pulling straight through and only ending say 1-4 of the cables at that box.

No angle or U pulls in that small of a box. They don't even recommend that short of radius bending of the cable if you want maximum performance out of it.
