I'm not so sure on the definition of plug and jack you have.
One can have most anything made.

A board of 100 jacks and a phone lady plugging in plugs to make connections.
She was pushing a male plug into the female socket in the wall.

Extension cords have both plugs on one end and sockets on the other.

That might be what your personal business's colloquialisms are, but
that's not standard usage.

I have cable jacks, and I have bulkhead plugs. The sex is the _only_
thing that matters.
