I was looking through the Graybar catalog and saw a different type of wire connector.

It's basically a collar with a set screw for clamping the wires together, then a plsatic insulator is screwed over the collar to give the finished appearance of a wirenut.

I like the sound of this: Sort of a cross between our screw terminals & your wirenuts.

Do any of you use these?
