I have 6 pairs of these for sale, they are ideal for panel/box mounting. I purchased them thinking they would work for my brewery layout, but unfortunately for me (fortunately for you) it did not. I needed flanged females. The flanged male inlet can not be wired to the "hot" side of the connection. NOTE THAT THE FLANGED MALE CAN ONLY BE ATTACHED TO THE LOAD!!!!!! For instance it would be ideal to mount the flanged male to the kettle and the cord and female end to the control panel. Cheapest I could find these were $38 per pair.
I'm letting these go for $20 per pair shipped.
