Chapter 7: Roof Assembly
IMPORTANT: The ladder assembly (A or B or C or D) and the manway hole (I or J or K or L) locations
must be determined before the center collar is positioned. The relationship between the
center collar channel clip (E), long center collar channel (F) and the spice plate (G) will dic-
tate the orientation of the ladder assembly on top of the roof. The possible locations where
the ladder assembly can be oriented are shown. Make sure to place the stairs over a rafter.
