QD Socket

Yesterday I learned that the near ubiquitous QD socket you see on almost every tacticool piece of furniture is a lot older than I thought.

Willard's father's Savage 99 has them embedded in the wood.  He indicated they'd been there as long as he could remember.

Of course, this is a piece of trivia that the internet does poorly at sussing out.  You search for the history and you end up with every vendor selling them.

The socket seems to date from 1948!

Everything old is new again!


  1. The ball/spring/plunger mechanism is pretty much the same as on the "remove before flight" pin and flag combo used in aircraft. At least US Navy aircraft.

    1. I had this style of quick disconnect on a fuel line on one of my 3-wheelers.
