Good to hear about the firewall ratings...

So now I can use the orange boxs. Good thing b/c I allready bought them.

All of the wall the 3" will run through have been changed to 2x6 construction to accomadate for the diameter.

How do you keep a bare coax or cat6 cable at least 1.25" from the stud face? Stud face being the face of the stud the drywall is screwed to? That seams impossible when the wire is dangling from the topplate all the way to the box.

Same questions goes if I were to use the smurf tube?

To coincide with ED comment my prints don't say anything about firerating walls.
