Anyone ever use one?
A jumper must be required from one of the screws. Otherwise, the screws pull the wedge tight into the conduit, but no reliable connection to the box is established.

Can't say I used it, as I have no clue what you are talking about.

It is a semi-circular grounding fitting that has 2 screws and can be retro-fitted around wires already installed in conduit by loosening the locknut and inserting the wedge between the locknut & the box. The screws are then tightened to effect a bond.

BTW,

I am not referring to bonding locknuts or bonding bushings.

Joe T. may be able to provide a picture(exhibit).

Try this

It used to be an inexpensive way to bond a GRC nipple between meter socket and disconnect.

So it's a sort of washer/flange in a way....provides better contact between the locknut and the sheet-metal panel the conduit is attached to?

That's what it seems to me...

I liked 'em for being inexpensive compared to bonding bushings. Just don’t forget that you need a {crimp} lug for the jumper.

They are useful. They are required ( I believe) when the conduit entering a subpanel is smaller than the largest knockout (?) There is a second lug to attach a jumper on the ones I've seen.

I have heard of them, but in my years of work, I have never seen one.
