Is it legal to strap (interior installed) EMT conduit using tie-wire?

And where is that defined in the code. Tell me does the code tell us what kind of strap we must use? There is no UL listing for straps so again I think the tie wraps are compliant. I see them used with MC cable all the time.358.30 says EMT shall be installed as a complete system. I would consider the emt strap part of the "system".

I use tie wire all the time for EMT and MC. It is efficient, cost effective, and does a good job.
What could be better? Maybe if it came in some fashionable colours that match my company's logo.
Show me a listing for the purpose on a one hole EMT strap or a blank plate, they may be out there but I haven't seen it.I would want to see the UL listing on the tie wire.110.3(B)

I had to do some demo at a job that the original installers used doubled up tie wire to secure the MC cables to the structure.
They did a very neat job and secured the cables well more than required. What a pain to demo, you had to use dykes at every support, there was no way you could rip it down like you could if they had used any of the Caddy / B-Line supports or tie wraps.
