I made this one.

I know it's an old thread. Can you describe the process?

The rib is probably strong enough to mount a box on. But if you feel that its not you could buy a piece of unistrut and span three ribs with it. Mount the box on the strut and go from there.

I have put a scrap block of wood behind thin siding to help hold heavy devices. I've even nailed headers behind siding.

I was thinking about this thread when replacing the cheapo jelly jar light on my barn last week.

I used a piece of composite decking to make a backing plate for the light.
