[SML] "Pipe Railing Fittings" style name...?

[Roger Bardwell]

Scott,

I think that Wagner Railings calls them "Ball Style"

*Hi all-

*I'm looking for the 'right' name to call some old threaded pipe connectors we have.

*Specifically, I can refer to the 3rd Edition of Paul Carter's 'Backstage Handbook', at the bottom of page 112 in the Materials chapter, under the heading "Pipe Railing Fittings".  If you look at the *drawings for Elbow, you can tell the fitting is of an bulbous shape.  So... What is the style name of this type of fitting?  These are classic parts and I'd like to label their storage home with the *appropriate classic name.
