This is a simple, strong hook that screws onto the corner of a 2x4. I'm making these hooks to fit on the underside of an existing shelf in my office. I'll be storing Interfit S1 studio heads on this shelf, and these hooks will keep them from moving around.

While the full weight of the lights won't be on these hooks, I still wanted the hooks to be strong, since the lights are very expensive.
