I assume you are running the main branch down the middle at the peak of the ceiling? Standard Y¡¯s should get the branch running down the slope of the ceiling, it¡¯s when you want to come off the slop and have a vertical run of pipe that the issue comes in, correct? Seems like a combination of two 45¡¯s or 90¡¯s at that point will get you any angle you want without resorting to custom fittings. I use spiral pipe and long sweep fittings, and have been known to cut one where I need to get whatever angle I want, then you rivet the short Nordfab rolled edge piece so you can clamp it to your other parts.
I have a lot of Nordfab ¡°joiner¡± pieces adapted to my spiral pipe to act like quick changes.

My shop has 9 foot sidewalls and vaulted ceilings. I am going to run the Nordfab duct up on the ceiling to maximize clearance overhead.? I have 3 options as I see it:
1) order custom elbows.? slickest solution but they need to be fabricated pretty accurately as the Nordfab does not seem to have any forgiveness once clamped.
2) do flex pipe for the custom angles.? The Nordfab rigid metal flex pipe looks perfect.? I need 7" and the min radius is quite large at 50" but that's not really an issue for me.? with this approach it would fit well for sure.
3) Do spiral wire poly hose.?
Thoughts, and has anyone dealt with custom angles?? Accuracy of Nordfab custom parts?
