I think I saw a variety of this a number of years ago when I was in San Antonio TX. They were made by Killark and appeared to be some sort of "interface" box between the POCO and the wiring/equipment supplied by the building owner. Never have seen the inside of one, though. There were various sizes, some large enough to contain fuses, and others which might have contained only lugs. They were surface mounted in all kinds of positions - right side up, sideways, upside down...

Thanks for the pics. [Linked Image]
