I use these hookers.That damn thing was useless at one spot. I put a nail into the wall thinking I would feel the meat of wood, but nothing.
I finally found a spot to screw to the old fashioned way, I put holes in the wall on the other side (it's a closet), until I found some meat.
You want that hook to screw into a lot of meat, so find a nice stud with strong wood. It needs to be able to support the neck coming in and out a lot.
You do not want that thing to come down on you.





Smooooth.
