The SmartBaffle Wind Blocker can be made many different ways as needed. But the most simplest is to cut the side flanges at the required distance say 7” and ensure the corrugated chute lines up on each side flange so the plastic baffle can bend straight. See attachments and directions. One can make multiple bends if wanting to make a nailing flange in addition to the wind blocker using the same method. Remember that the flanges bend in both directions as needed.
