You can't find it because it sounds like you are going the wrong way.

What is your application?
Of course, you can build one up by buying the components and a short AC cable.

Good find, Djones, I had forgotten about those professional, rack mount power strips.

@djones51 - Bingo! I swear I looked for 45 minutes and "nada".
I have two sweet RELs coming tomorrow and planning to use a 3 meter Shunyata Venom HC (20A) for power. I opened it up today to install a 15A female connector but found Shunyata put some kind of goop (in the factory it’s called "snot") to prevent the screws from coming loose.
Didn’t want to de-goop it and decided to go the converter route.
Thanks for the help Audio Dudes!

P.S. Just found it on Amazon. Guess knowing what to call it is more than half the battle!

op:  The goop is often some flavor of Loctite.

Got the converter today and it snapped right on! Like it was made for it!
