What are these landscape 'hooks'?
I have a house that came with these "hooks" attached to the wall with what appears to be silicone, or some sort of adhesive. I want to use these hooks to build my own trellis on a cinder block wall to have vines grow up the wall and trellis.
Does anyone know what these hooks are called, and where I could get them?
I've asked at the local hardware store (Ace) and Home Depot to no avail. Any help would be appreciated!
