When I ran flex duct to the cans, I just pulled the inner liner over the can, tie wrapped it and shot a tech screw through the tie wrap into the can, about 180 degrees from each other. Duct never slipped off. I saw a lot of ductwork slip off the can even with the tie wrap installed, and taped but no tech screw. Good job by the way tidybuoy…
