I am curious how people are installing these specifically on steel insulated doors. I have 10 foot wide doors, and the manufacturer says there are only ribs at the ends and middle, making most of my door unusable if I need to screw directly to the ribs. I am curious if anyone has screwed just to the metal skin and if it felt secure.
The only other thing I can think to do is to add some 1/4" material the full width of the door in order to hit all 3 ribs.
