The J-hooks on the ends are screwed into the wood framing. The J-hook in the middle is screwed into the ceiling which is much less substantial.
I'm considering adding a cargo net in the bathroom in front of the open shelf over the toilet but there's no wood framing. I may add a strip of finished ~1x2 from the shelf to the ceiling on each side by gluing it, then screw the J-hook into that. The glue covering a larger surface area should be stronger than the J-hook pulling on a single point.
