small internal overflow boxes

I was wondering if anyone had ever used those small internal overflow boxes before. I think I may have talked to offshore about them at one time. thanks

I use two 1.5" BH holes with a small internal overflow made out of black acrylic. There are teeth in the top for water to flow in. The store I work for uses the same design. Works great, and IMO is safer than external.

do you have any pics of your set-up? I have two 1" bulkheads with 90's on them now and was looking into these so I could turn my 90 downward and not overflow my sump.
