It will be an elipse or oval approx 4.25 inches (diameter of pipe plus clearance room) on one axix and the other axis will be ~ 4.25 divided by the cosine of the angle of the roof. Example: 45 degree roof has an oval cut that is 4.25" x 6" inches (cosine
of 45 is .707 4.25/.707 = 6)

Hey srazor. You're starting a new thread instead of posting a reply.
Please see if you can keep it in the original thread.
