This is what is being used. All tie wraps for every box and wire in the place.

Home made devices? In Florida those are called "similar fittings".

334.30 Securing and Supporting. Nonmetallic-sheathedcable shall be supported and secured by staples, cable ties,

straps, hangers, or similar fittings designed and installed so

as not to damage the cable, at intervals not exceeding 1.4 m

(41⁄2 ft) and within 300 mm (12 in.) of every outlet box,

junction box, cabinet, or fitting. Flat cables shall not be

stapled on edge.

Sections of cable protected from physical damage by raceway

shall not be required to be secured within the raceway.

Designed and install by true Florida craftsman.

I would have no problem with the install pictured.
 
My electrical inspector told me there are accepted tie wraps those whit a metal finger in them and the all the others, sorry no code reference, I asked him one day
 
me too.. just because it's not what we expect to see doesn't mean it doesn't comply with the intent of the code.
 
It appears NFPA is saying that the strapping of NM is just to keep it out of the way of the sheet rockers and after that is installed, strapping is no longer necessary. 334.30(B)(1). If these methods accomplish that and last that long, they seem compliant.
 
I don't invest in the NEC handbook, which usually has a little more explanatory information. Doesn't really matter why the Code requires it...
