Reply to comment by knowitallz in Ducting for under cabinet range hood, how to offset to get by stud? by ninian1927

It's a load bearing exterior wall so I'm not sure, beyond my comfort level really. I guess my question is, would only using two 45s still allow me to offset a few inches to the left and then out? That's the part confusing me, the duct cutout in the hood is directly in middle of it ( on top), so I need to start there with duct, go left a few inches, and then connect to the exterior wall vent duct which will be likely at top (inside) of cabinet

Then go left with two 45s and go out. 45 is just a less of a quick turn. Less noise by a lot. I have a straight shot with 8 inch pipe straight up and run a 900 cfm fan that has 4 settings. I cant hardly hear it at full blast
