That makes two of us, I never saw one till I dug this one up.
This one had to many 10 AWGs.
Story
here Zinc, (or aluminum)... which is what they're made of... don't handle alkalai very well. They quickly degrade to little more than white dust. I am surprised they're actually sold in concrete- an alkalai.
I agree and the one I dug up is only a few years old. It is already junk as far as any threaded holes.
The one in the pics was certainly in poor shape. Every such box I have seen, either buried in concrete, or just buried in dirt,
has been seriously corroded, and filled with mud. This is true even when the cover appears to have a gasket, and be properly installed.
Again I agree.
I replaced this arrangement with a handhole, and traffic-rated cover.
Cool.
