What am I looking for?

OK, so I was given a Manfrotto boom stand a while ago, but I am needing a part for it and I have no idea what it is called.

The tripod is an older one of these: http://www.bhphotovide​o.com …nvertible_Boom_​Stand.html

Here's a pic of the junction that I want to make: http://i.imgur.com/XeM​XOHh.jpg

Which is basically requiring a double ended version of this: http://i.imgur.com/V0W​mo4x.jpg

But I have no idea what to search for. What do I call this thing?!

5/8ths double ended baby pin.

edit: that's just an umbrella swivel you want to put on there, right?

in the first link you posted go to the what's in the box and they show you the part, they call it a spigot, same thing.

It is not clear what you are trying to boom, but depending on what you are putting on the end of your boom a DROP DOWN PIN might be of value. I use one when I am working with a beauty dish.
