Ç p

— 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

. 

r

— Enters or calculates the 

Rise

or vertical leg

(height) of a right triangle. 

R

—Enters or calculates the 

Run

or horizontal leg

(base) of a right triangle.

d

— 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.

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.).
