I like it a bit better because you can lock it in multiple positions. Here is what I am trying to accomplish..

The top box is not currently attached to the canopy, the previous owner removed the top of the canopy and then suspended the top box from the ceiling. I don't want to do this, so I am going to cut a hole in the top of the canopy and then use brackets to attach the top box to the top of the canopy. But this will make it heavy and also not something I want to be going upside down since it has my lights inside of it. I want it to be able to lock into place at anywhere from a 45 - 89 degree angle max. This way it doesn't get to heavy on the back side and flip off against the wall.
