Thanks for the replys. Good to know about the spray from the other thread steves. Guess I'll find out some more at the job.
The whole engineered fire stop system I get, just seems counterintuitive to me that I have to make a hole at a minimum twice as big to put in a sleeve, that on the O.D. is not any differently handled than the conduit would be. I imagine there is a reason it is needed and I am hoping someone can explain.
Have looked at the hilti site, but did not take the time to register yet and go thru the tutorial. I did not figure it would give as much why information as it would how. But I guess I will not know until I look!
