RAKE-WALL - FIND STUD LENGTHS &
ANGLE OF INCLINE
Example: A rake-wall features a base height
of 7 Feet, a peak (rise) of 5 Feet, and a length
(run) of 10 Feet.
Determine the stud lengths and calculate the
angle of incline for the rake-wall.
For this example, assume you are not using
the standard On-center spacing of 16 Inches,
but instead are using 14 Inches.
