It doesn't even look like those covers fit those boxes.
If they were metal and the hubs were threaded, there would be no need for the locknut at all unless threaded too loosely into the hubs ?
If they are metal then it looks like they drilled them out and used locknuts and silicone as a band aide.
To me they are either metal boxes where they drilled the side out that didn't have the hubs or plastic boxes.
