two questions: (1) listing shows "3" different adjustable lengths, i wonder which is correct?--- (2) can the rubber dividers be adjusted?

Does it work well with a 40" space?

I wonder if getting two of them would work for fishing poles?

Why does this say it holds 30 lbs in one area of description and that it holds 50 lbs in another area of the description.
