Jim,

I am guessing you might be right.  However, the Mfg. Sales Rep
said it was a US Standard.  I got more specific with him and
he said he would have to check with the home office.....
in Korea, and was to get back to me......... yesterday.......

Thinking he lost my number........ I am calling again today.

Boggles the mind!!!  Oh, I am trying to type NICELY!!  :-)
