It is concrete wall. The detail on the contract drawings shows the
coupling at 6" inside of the secure area. I think what we have will
serve the purpose.

True, in my case they did, but if they just specified coupling on Travis'
job, maybe they know the break will avoid the entire system being one huge
antenna. Hopefully the wall is not metal stud!

And it may be they need non-metallic the length of the wall thickness

Good deal-- Ron F. idea of di-electric would probably work physically-- stop
the flow of electrons-- but they are not 'non-metallic'.

I was able to calc it down with a short piece of 3" CPVC pipe. Then just
use the CPVC x Grooved adapters. Hopefully this will fly. It is all light
hazard.

Do you mean the room is some kind of secure communications? I did one
recently- No metallic PENETRATION of the walls- (like an antenna) - I

a non metallic coupling would be like breaking the antenna- I went
steel
up
to the wall, steel to cpvc, cpvc through the wall, then back to
steel. Is
4"
cpvc made?

Subject: NON-METALLIC COUPLING
I am working on a military project. I have to provide a non-metallic
coupling on one side of wall. It is a penetration into a secured area.
Any ideas on what to use as a non-metallic coupling for 4" sch 40 pipe?
