Adding an external ground to 2" LFMC

[Carl24x]

Looking to see what could be used to install an external ground on the outside of a piece of 2" LFMC in a class 1 Div 2 area. My flexible connectors do not have provisions to install a ground on them and are too thin to tap. It's been a while but i recall using something split that you could loosen the nut, install and retighten connector providing a means to install a ground. I wanted to see if anyone recalled the part i'm looking for while i continue to look.

Thanks,

I found what i was thinking of using. Not sure if you guys have used them but a grounding wedge is what i was thinking to use here

Thomas & Betts makes a LTM connector with a ground lug, and a ring that camps over the fitting to take an EGC, I used to stock all the sizes of the rings.
They would be special order but a distributor like Graybar may have in their system

I was able to find a T & B grounding strap that fits over a their connector but it only goes to 1 1/4". we were able to tap it out and install a machined screw. Looks like an after thought but it's better than a tek screw.

Thank you
