The functions in detail: - Menu with preset times for quick selection - Individual timer with minutes and seconds - Simple operation, just as it should be in the kitchen - Settings for preset times, alarm sound, duration of the alarm tone and language

Stair Stringer Calculator lays out a straight flight of stairs from three measurements and tells you how to cut the stringers — in carpenter's fractions, not decimals. Enter the total rise, the tallest riser you'll accept and your tread depth. You get the riser count and exact riser height, the tread count, total run, stringer length and stair angle, plus a to-scale drawing of the cut stringer. CUT IT RIGHT • Riser height is rounded so it never exceeds your maximum • The first riser cut is dropped by your tread thickness, so every finished step is equal • Framing square settings and the step-off distance along the board edge • Notch depth and the solid wood left under the notches (throat) for a 2x10, a 2x12 or any board depth • How many stringers to cut for your stair width, and their spacing • Type measurements the way you read a tape: 108 1/2, 9' 0-1/2", 7 3/4 CHECK IT BEFORE YOU CUT Every layout is checked, and the result shows what passed, not only what failed: • IRC R311.7: maximum riser 7-3/4", minimum tread 10", maximum rise of one flight 151", minimum width 36", nosing and handrail requirements • AWC DCA 6 deck-stair stringer limits: at least 5" of throat, a 6'-0" maximum span for cut stringers, stringers no more than 18" on center • The stride rule 2R + T for a comfortable stair (24–25 in; 590–650 mm per DIN 18065 when you work in millimeters) FULL CUT LIST AND PDF • Height, run and board-edge mark for every step • A PDF layout sheet with the drawing, cut list and code check for your crew or inspector • Unlimited history: reopen any saved layout with its drawing and checks INCHES OR MILLIMETERS Switch units any time.
