Hi, I recently installed 2 metal house support polls.. you know the kind you put in your basement of old homes to help support floors? Well as I was reading the directions it said to put the crank part at the top for steel and at the bottom for wood floors.. was just curious.. why is this?

Supporting steel doesn't require a base plate as rigid as wood, therefore the plate welded to the tube will spread the load more effectively on wood. HTH

I have totally no clue.
However, my father the editor would have reminded you that a survey is a poll, and a vertical shaft is a pole.
