[GreenKeys] Twist-Lok Twist-Tite was: RA87 and BE-77-A

[Steve Schlink]

Gary,

How about the dimensions?
Photos?

A few minutes of googling led me to this:

So, Twist-Tite was a Bryant  tradename. Bryant was bought by Westinghouse 
c. 1970. Westinghouse has long been out of that business.
It looks like Hubbell now owns the Bryant name. I doubt that any of the old 
Bryant people are now at Hubbell. One shot is to call Hubbell and ask for 
the oldest person there. He at least might remember the Bryant receptacle 
and know whether there was any interchange.

You are short on options. (The worst of which you are now doing - cramming 
the wrong diameter cap into the receptacle.)

1. Remove the existing receptacle and hardwire a cordset.  At least then 
you can carry the receptacle around with you and try any you might find. 
Then when you hit the lotto, you can have one manufactured. And it is 
reversible.

2. Replace with a more common Hubbell Twist-Lok. At least then the chances 
of finding the cap are reduce from 1-in-10million to only 1-in-1million. As 
I stated earlier, Western Electric Bell System used a 2 wire Hubbell 
Twist-Lok receptacle on some of their equipment.

3. Enlarge the hole so that a safer 3 wire current 
Twist-Lok  receptacle        can be installed.

While I usually shun modifying original equipment, I think that that the 
safety issues justify #3.

So after all of this, now I have another thing to look for at estate sales 
.... I wonder how many I have stepped over?

Good Luck,

Steve
