A tool used to determine the appropriate dimensions and spacing for the angled supports of a staircase, specifically those attached to a deck. These supports, often called carriages or cut stringers, bear the load of the stair treads and risers. An example application is determining the precise number of steps, rise, and run needed to safely and comfortably connect a deck to the ground.
Accurate calculation of these supports is critical for ensuring the structural integrity and safety of a deck staircase. Proper dimensioning prevents uneven steps, potential collapse, and costly repairs. Historically, carpenters relied on manual calculations and experience; the advent of digital tools simplifies this process, reducing errors and saving time, while still adhering to building codes and safety standards.
