Why do I not have ideas like this!!??
Roll a silkscreen with some blue ink on a $7 spec-grade 20A outlet, then charge an unknowing, over paid sucker $147. Genius!
I only say $7 instead of $2 because this looks like a back-wired screw-down receptacle, which tend to be a tad more pricey.
(BTW, the answer is that I'm not a crook. I prefer to work for a living)
