This component encloses the space between two adjacent treads, preventing feet from slipping through and providing structural rigidity to the staircase. In closed-stair construction, it is usually glued and screwed or wedged into a routed stringer. The height of this piece dictates the vertical elevation of each step, which must remain strictly consistent to meet building codes and prevent tripping.
