Hip/Valley and Jack Rafter Keys

The Construction Master Pro uses the Rise, Run, Diagonal, Pitch
and On-center spacing values to calculate Regular and Irregular
Hip/Valley and Jack rafter lengths (excluding wood thickness, etc.).
Pitch Ratio or Slope (Slope) — Enters the Pitch as
a ratio or Slope of a roof (or right triangle). For
example, 0.58 slope is entered as • 5 8 Ç
p.
Rise — Enters or calculates the Rise or vertical leg
(height) of a right triangle.
Run —Enters or calculates the Run or horizontal leg
(base) of a right triangle.
Diagonal — Enters or calculates the diagonal leg
(hypotenuse) of a right triangle. Typical applications
are "squaring up" slabs or finding common rafter
lengths. Additional presses of the d key will also
display plumb and level cut angles in degrees.
Note: The Common rafter calculation is the "point-to-point" length
and does not include the overhang or ridge adjustment.
