What should I use to sexure flex conduit...


I have 3/8 flex conduit I need to secure to a brick wall, the problem I have is finding a strap or device to secure the conduit to the wall. I can only find sizes from 1/2.

Should I ditch the 3/8 and go 1/2?

Look harder. Home Depot and Lowes both have 3/8" straps. They may be in the section for bx/ac/mc fittings area.

Alright, I will look harder. Sometimes they stock the times all over the place so its hard to find what your looking for.

Thanks for the help.

I am very lucky, A 20 minute drive from home puts me at Lowes, Menards, or Home Depot, and they are all close to each other.

I guess you can always order online.

Isn't a furnace exposed? Wouldn't it require EMT or other conduit system that is rated to provide protection from physical damage. I remember asking KC one time about using a BX whip to my furnace and he said it should not be allowed. So I replaced it with EMT.

EMT is getting really cheap, under $2 for 1/2" now.

Its tucked between the furnace and the wall, not sure if its considered exposed. I could try emt.

Its about a 30 min drive to those places, guess I just don't like going there.
