RAKE-WALL (NO BASE) - FIND STUD LENGTHS & ANGLE OF INCLINE
Example: A rake-wall has 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. Use standard On-center spacing of 16 inches.

4. Caculate the angle of incline:
Note: By setting the Rake “Ascend” Preference, you can view the stud lengths from smallest to largest.
*Note: You can also solve for stud lengths using inputs Rise and Pitch, Run and Pitch, or Diagonal and Pitch.
Simply enter the known values using the , , , or keys, similar to Step 2.
