Now stand each upright ladder into the holes. (Next step works best with 4
people but can be done with as few as 2 strong adults). Have one person on
each side of the horizontal ladder and lift it to the proper elevation while the
third and fourth people push each upright ladder into the horizontal, as shown
below. (With only two people, have one position themselves in the middle of
the horizontal ladder while the other places upright ladders into place.)
Ex: Have person #1 secure upright ladder to the horizontal with one ⅜” set
screw. Then person #1 goes and places the other upright ladder into place
while person #2 continues to hold horizontal ladder.
