Yes he did and I have done it as well. I would cut it off right behind the shoulder of the fitting so it had a lower profile inside the box.

starting soon Illinois will be putting a $1000 tax on each ground rod used in Illinois to pay for state employee pensions that are now something like $150 billion in the hole. CEE's will be $500 each.

Look for an increase in use of CEE's and structural steel as electrodes then.starting soon Illinois will be putting a $1000 tax on each ground rod used in Illinois to pay for state employee pensions that are now something like $150 billion in the hole. CEE's will be $500 each.

Just a wild idea, but the crimp would be considered an irreversible bond if for some reason that mattered.
It is also mechanically stronger and is less likely to come apart from vibration.

When we get to the point that using set screw fittings makes the job look uglier it's time to quit IMHO. If you were to say that indenter fittings make a better and more reliable fit I might buy into that.
Maybe so but it's one more tool you'll have to carry on the job.

Indenter. I actually prefer steel set screw fittings over compression fittings, but it is very rare when I run anything other than rigid. Most of the specs that I saw back when I was doing commercial work did not permit either indenter or set screw for EMT.

My preference as well. Most facilities I end up working in that originally were designed by an engineer firm usually had compression fittings also - probably was specified. I find a lot of fittings that are not tight. Set screw fittings often you can tell just looking at them if they were tightened or not easier then you can most compression fittings. Also seen a lot of broken die cast fittings over the years - set screw or compression. Many times poor raceway support was the main cause of this although steel fittings will still take more abuse.

very rarely I will use one when coming out of masonary wall into surface mount box, crimp to emt and slide back into hole, just a little easier to not have set screw or compression nut to fit into hole

It is my opinion that the indender fittings makes a much cleaner installation than either of the other two options. The key word is "opinion".

Seems like an awful lot of unnecessarily installed paraphernalia just to bond a ground wire to a pipe. I can understand the local codes requiring line voltage conductors in conduit but I don't understand the necessity for a ground wire to be in conduit. If you think about the amount of work and materials involved in doing this (the breaker panel is about 10'-15' away) it makes this seem excessive to me.

Whether the GEC is required to be in pipe or not is another issue. If it is in a ferrous pipe - it must be bonded to both ends of the pipe - that fitting is designed to bond it to the end of the raceway and also has a semi flexible strap to extend to the other pipe being bonded to.
Without that fitting, the most popular setup is a grounding bushing on the end of the raceway, loop the GEC through the lug on the bushing and then over to the water pipe.

Again, I have never seen one of these and that's why I posted it. Is this common practice in Nebraska or other states or is it just an IL thing ?

Hardly ever see GEC's in metal raceways, but have occasionally seen similar fittings.
Since Chicago requires a lot of metal raceway - I wouldn't be surprised if you see more fittings like that in that area.
