The 5 Precut Stair Stringer is a set of five pre-cut stringers designed for constructing staircases. Each stringer is pre-cut with notches to accommodate the treads and risers, ensuring consistent spacing and alignment for a stable and safe staircase. These stringers simplify the stair-building process, making it easier to achieve a uniform and reliable structure. They are typically made from durable wood or metal, suitable for both residential and commercial applications.
