Our AHJ is now requiring the use of a "kenny clamp" for GEC. What alternative products are available? Also, if there are two GECs (water bond, ground rods) then I assume two kenny clamps are required?

What are they?
 
There is no reason to use a clamp for a GEC except to line the manufacturers pockets, I know that doesn't help with an overzealous inspector or AHJ. Before I would buy a Kenny Clamp that has been deceptively marketed to be a code required item I would sleeve the GEC in PVC.
 
I agree with Roger they are not required by the NEC. If you use them then it has to be with the listing of the Kenny clamp which tells you the size and number of conductors permitted.
 
I've never used a Kenny Clamp but from the data sheet it appears you might be able to use one at the end of a metallic conduit to satisfy 250.64 (E) without a bond bushing/bond jumper.

The GEC (grounding electrode conductor) from the system grounding comes out of the meter or panel. We are required to provide a way for utilities to attach their ground to the system ground. The item shown allows the GEC to go through it and is clamped by a screw. The other screws are ports for other ground wires to connect to. It is called an inner system bonding bridge.

This issue with the Kenny Clamp has come up before, The general consensus here is that it’s not required.

Thank you, Sir!
 
Didn't we run into this before with an inspector making the electricians use kenny clamps. Probably the same guy who got fired from his last job and ended up where the op lives. hahaha
