What's a Kenny Clamp?

As far as the Kenny clamp , There are less expensive listed products on the market. Arlington Industries makes 2 and I believe Bridgeport makes one.
NM connectors are not listed for a single conductor. They are only listed for type NM cable. that's the issue with using NM connectors for the GEC.

It is posts like this that really get me thinking about stuff that we have done for years and have never really thought about it. We cannot just drill a hole in a meter socket or panel; stick the wire in and tie it in. Did that a few times over the years and the inspector stated without hesitation that you must use a connector when entering a cabinet or box… so off we go using a plastic or two-screw connector… and the world continues to spin effortlessly…
Then someone comes along with the simplest response like, the plastic or two-screw connector is not “approved for use” with a single conductor… and they are absolutely right! Then I think, why the heck did I not even think about that?… I just merrily going about my business using these non-compliant connectors all these years and never once did it occur to me…
Thanks! Now I am not going to sleep tonight… this is almost the same as using flush mount covers on a surface mount box… My historical defects are starting to pile up! I might have to change my screen name to The_Hacker or something…
Cheers

Why not?
Many panels have a small hole for that purpose. And there is nothing stopping us from making our own holes.
The GEC is different than everything else. Support, burial depth, etc.

Busted! I'll be alerting all the inspectors in your area first thing tomorrow morning that you are altering the UL listed equipment by drilling a hole in it. A clear and present danger and obvious NEC code violation.
Per the NEC, the GEC has to be BONDED when it passes through a ferrous enclosure.
This was detailed - by me - in a thread less than two-weeks ago.
And, you can't bond with plastic.
Two-screw Romex// MC connectors are NOT listed for this application, BTW.
I know, I know, they are commonly thrown at the 'problem.'
&&&
But hey, as long as your AHJ is letting you get by... why obey the NEC ?
The danger created only erupts when fault conditions fire off, anyway.
Until then, everything works perfectly.
Hey, that's the same logic as every DIY// handy man out there.

Post that article.
Link?
We are abiding by the NEC, which does not require the GEC to be bonded as it enters an enclosure. The only thing even remotely close to what you are saying is that the GEC needs to be "choked" as it enters and exits a metal raceway.
No, your logic of saying things are required without citing the code is what handymen do.
I'm getting fed up with people throwing out so-called code requirements without being able to show us where the code requires it. Next I am going to start handing out smacks.
No, using any of those is a waste of money, effort, and natural resources, run it though one of the factory supplied holes or drill your own and land it in a lug bonded to the enclosure.

The GEC has to land on the neutral bar.
The exception is that you can land it on the ground bar if the main bonding jumper is an appropriately sized wire or busbar.
Landing the GEC to a lug bonded to the metal enclosure when the main bonding jumper is just a screw is not compliant.

That code is talking about terminations of gec . 250.24 .4
My post is relating to this connection being made in the meter can which is the norm in the Southeast. The lug I'm referring to is the factory supplied Neutral bar in the meter can which has provisions for the GEC along with the line and load side neutrals and is factory bonded to the enclosure.
If that is not available, I agree that you would need to make the connection in the Main service equipment and that would be on the neutral bar or combination lug.
IOW's, we are on the same page.
