Sorry I do not have photos. In my current home, I fed the box from below, so it's different - no rain hub, just the adapter nutted in as Roger mentioned.
I just took a look at a few risers coming up out of the ground. Some are Carlon, some are JM... sunlight resistant... with UL spec number. Some are old, some new. It all seems to be holding up fine. Most of the rain hubs I've used over the years are diecast pot metal (a catch-all term for cheap zinc diecasting alloys) and they all seem to be made by just one or two places that supply them to Square D, G.E., etc. Again, they seem to work fine. PVC conduit fittings are likely Chinese-made... ugh... but then again I've used a lot of them over the years that I just get at Home Depot and never had a problem. If there was an electrical supply house close that had USA-made fittings, I would go there on general principle.
OK thanks all you comments are thankfull. If any one has any pics pleas let me know.
