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.).
18 — C

Pitch Ratio or 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.
Enters or calculates the rise or vertical leg (height)
of a right triangle.
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.
