Punch a hole in the top and use a fitting listed to seal water out, that might be as fancy as a Myers hub or as simple as a sealing o-ring.

I might be missing exactly what your asking, 3R enclosures don't usually come with any prepunched KO's due to their rating...

If you coming out the top you need a myers hub. Now you got me thinking if it required also out the sides as well ...

One can look at these two sites to get some other ideas :

Hoffman

or

DDB (which is a quite more varied)

All of the 3R disconnects and panel enclosures that I have seen have prepunched KOs. I don't think I have ever seen a 3R pull box.

You do not have to use a Myers hub, that is one option among a few.
