For years I've used galvanized tie wire to strap down mc, emt, etc., and I'm sure there used to be something in the code that said it was an approved method, if doubled or something.
I heard today that it went out in the early nineties and that tie wire is no longer an approved method. It seems like they have added cable tie wraps into the mix as an approved method, but don't say anything about using the fire rated red ones in the ceiling.
Can someone straighten me out on this? The inspector said if I could show him that tie wire was approved, he would accept it.
Tie wraps are easier, but way more expensive. I think the red ones are around $1 apiece, although I saw some metal type ones in Home Depot today at around $5 for 10. Would that work in ceilings?
I think the inspector would approve regular tie wraps in the ceiling but I know the red ones were required when I did some LV work.
