Help with ID


I found these in the crawl spaces of a home that had drain tile and sumps retrofitted. The single is in a smaller addition crawl and the set of three are in the main crawl. Anyone know what they are?


We’ll I can’t read the labels so I would only be guessing

The labels where just white, nothing on them.

Looks like flash washout to me but I wasn’t there.

I think I see text in the circle and what’s going on with the unterminated fitting?

Where was this located? (deck, crawlspace etc.)


There was no text on the white label if that is what you are referring to. The location is in the crawl space.

They look like Radio Shack project boxes

If it were me I would ask the owner/seller for information.
