Once again, Greg provides moronic advice about his personal preferences in electrical installations. So what if it violates code and uses products in ways they were not designed for. Professional electricians know how to install a complete conduit run (as required by Code) and install the conductors without damaging them. Trolls think they are smarter than everyone else and their way is the best way.I personally like the longer El's for pulling, than those short ones. It gives you a little wiggle room. Also helps in something like this, as you know, not to screw the box down until the end. I tend to just pull the wire, put on an El while pulling the wire through, then attach it to the EMT, repeat until you get to the box.
Keep trolling Greg.
