Did you go from inside the duct? How hard was it to get it back in later?
I came in from the top. To put it back in I used a small piece of blue painter's tape to help hold the screw to the tip of the screwdriver. The screws on mine are in between the slats running long ways.
I couldn’t find the screwdriver I usually use but this is the same method. The other sd is even longer
