[GreenKeys] Hubbell Twist-Lock Help (evidently "Twist-Tite")

[John, W9DDD]

That's a bit wild.  Why the L hook then?  Perhaps some planned mating 
plug with a polarity hook on it that didn't become popular enough to 
become a standard?  Can't say I've ever seen the male plug that would 
have been designed specifically to be a twist lock rather than parallel 
blade to fit that, and I spent 10 years in a plant that was full of old 
stuff.

I have to say I've never heard the term twist tite before and I worked 
with a bunch of electricians 30 years my superior.  They always said 
twist lock in reference to actual twist lock and old terminology tended 
to last over new.  So it didn't seem to be in their vocabulary either.
