Well, I was referring to the end that goes on the wire :)

I have one right here. I much prefer the one with the screw terminals; The
push-on-lug style uses the smaller harder to find terminals and not the
standard 0.25 inch terminals.

OK, Speak-ons do come in a variety including an AC power version with
heavier contacts. I used the standard 4 conductor as it has plenty of metal
for the current in MOTM DC.

I can address a little experience here too. The hole size on all the 4 pole
speak on's is the same. But, the barrell size is 0.93 inches. So, a perfect
US hole size would be 15/16" drill size. Now, I own a fair amount of drill
bits. Once you get above 5/8" they seem to come in 1/8" increments instead
of 1/16". So while I have been able to find 9/16, I have been unable to
locate 11/16, 13/16, or 15/16 inches to fill in the gaps in my dill
collection.

The point of this is that some of use may be foreced to drill a 1" hole.
The size of the eschusion and mounting hole pattern makes the 1" hole very
close to too big. However, the Speak on connectors that have the round
flange, have ample room to allow for drilling of a one inch hole.
