I've taken a quick look and it's only Eaton that offers this nifty little add in. Leviton and Pass and Seymour don't.
"I also don't use the stripping gauge since I loop the wire around the screw."
The wire stripping gauge on the outlet gives you the proper strip length for either backstabbing OR looping around the screw.
Or, in the really cool outlets (which I always try to buy), the screw compression plate.
"As my dad said a few times: "Amateurs poke. Professionals screw""
I agree 100% with your Dad on that. I HATE spring clamp backstabs. They don't hold properly, they're prone to failure, leaving an open circuit and dead downstream outlets, and I've seen evidence of arcing in more than a few I've pulled over the years.
About 10 years ago I came here with a question trying to diagnose intermittently dead outlets in my three bathrooms.
Turned out to be a failed backstab... on my outdoor patio outlet.
The wire routing was -- Electric panel -> GFCI outlet mounted next to the panel -> outdoor patio outlet -> outlets in the three bathrooms.
Obviously they did it that way to get GFCI protection on all of those outlets when GFCIs were new and expensive as all hell. But it took me awhile to figure out.
As I noted above, though, the clamping screw plate backstabs? Those are the absolute tits.
