Quite a while ago someone posted fitting/lug that could be used to bond the grounded conductors to the cabinet without cutting the conductors.

I bookmarked it but it must have been on the old computer. Anyone remember what that was?

Was this a fitting to combat choke?

No sir, picture a PVC conduit install between CT cab and main disco. I run EGC's back to the CT can.

It was a pretty slick deal for bonding the can.

I thought I knew what you were talking about on the first post now I am clueless.

This is what I thought you were looking for but I think this is not what you want.

If I have 3 sets of 600's passing through the can, I would like to bond the can without bringing 3/0 EGC from the main back to the CT can.

Why not use a NSI block there about $55.00. thats what I use on My CT cabinets. I'll see if I can find a pic
 
I always used a "stud kerney". Its basically a split bolt with a stud made onto the head so you can bolt it thru your cabinet and lay your grounded conductor in.
 
A little off topic:

Why does the neutral bus in a CT can have plastic insulators under it?

I question this everytime I run a bonding jumper from it to the CT can, if I could just remove those insulators(legally) and bolt that bus right to the can I would not need the jumper.

I'm sorry, we use doughnut pass through CT's here.

Around here the neutral gets bonded directly to the can. There is no EGC on the line side of the service disconnect.
