There are many hooks that attach to drywall or wood surfaces with a nail but this one is different. To use this part, press the flat side against the wall with the hook angled upward and hammer a two-inch finishing nail into the hole. I chose to design this with finishing nails in mind, but any nail long enough to penetrate the drywall with a girth of 2mm or less should work. Keep in mind behind the drywall could be electrical wires or metal plates so do your research first before you use this to make sure you are mounting it in a safe spot.
