Jiffy clips if one run, CJ's if more than one run, and laced if using a drill would be a pain for whaver reason.

I'm not sure I understand. Have you never used one-hole straps on MC cable running parallel to framing members, tek screwed to the stud? Caddy makes a fitting along the same theme that just clicks on the holes in the stud. CJ's are about 50 cents a piece, and when you have one cable, it seems like a bit of a waste. A jiffy clip is about a nickel.

Kind of interesting, I just noticed it has the note.

I've used a 1-hole strap....thought jiffy clip was some slang/trade name (like CJ)..never used one though.

For the price...I just stick with CJs...less stock to keep track of, less wandering about to find specific parts, etc

Yeah, that fitting probably does have issues. At least with a Jiffy clip, you can fix the cable in the middle of the stud, taking care of the 1-1/4" issue.

I have no idea what a jiffy clip is if is not the clip I pictured.

Who makes it?

Lots of companies...

"Founded in 1894, Minerallac developed and patented many of the most common parts used in electrical construction today. This includes the Standard Conduit Hanger in 1904 and the one-hole strap "Jiffy Clip" in 1913."

It's just a one hole clip for MC, not very 'Jiffy' to me.

I have some in the truck, I only use them as a last resort.

Lace all the time we even teach how the stud is punched from a particular direction therefore easier to pull wire in this direction. Also wire is wound in a particular direction also pulling easier in one direction. lacing is fast and cheap. Some use the cut off casings of the mc and tie it thru the hole in the stud with tiewire not laced so the cable will move when hit with screw. I use this method also
 
My question was, how does one comply with the 1 1/4 inch requirement of 300.4(D) when lacing the cable vertically up or down the framing member?
As an inspector, that is one of the items we can easily see when walking the site. If I see it in the web with less than 1 1/4 inch, am I supposed to say it is okay? It will get flagged...how would you handle this situation if I was to inspect your work? I am open to any who have a professional response.

Lets not forget that inside of the web is the most likely place for a screw to be installed, as most sheetrockers try for that location.;)

Lacing in a standard stud is 3 1/2 thick plus the 5/8 rock on both sides builds you a building a 4 3/4 inch wall minus 1 1/4 x 2 =2 1/2 '' for screws. this leaves 1'' space without considering the rock and 2 1/4 " if you can incorporate the rock in your figure.
 
i personally cant see the difference, having said that i hate the stuff. pipe takes a little more time but is so much better. and that maybe just brain washing the local inspector here dosent allow it other than for lighting whips.
 
I've run EMT through walls in commercial retail applications (metal studs...hole punch as needed....no big deal).

How difficult would it be to run EMT in a new stick built home ...assuming of course, that you have prints, can bend pipe, etc ...basically have a clue about running pipe....as compared to running NM or AC?
Time wise ....including pulling/splicing? More time, same, less?
Cost wise (material and competant labor)? More, less, same?

I can see where EMT would have it's advantages....but it all boils down to the numbers here.
