Abstract
A novel step bracket is provided and is adapted for securing a step in a horizontal position to a downwardly sloping stringer. Preferably, the bracket is formed from a sheet of metal and comprises an upper horizontal portion secured to the bottom surface of a step. A generally triangularly shaped vertical section of the bracket extends downwardly from the horizontal portion and a flat portion is formed along the bottom edge of the vertical section and is perpendicular thereto. The plane of the flat portion is skewed relative to the horizontal plane so that the flat portion flatly abuts against the upper surface of the stringer. A downwardly extending vertical lip is formed along one edge of the flat portion section so that the lip flatly abuts against the side of the stringer. Fasteners are then used to secure the lip and the flat portion to the stringer and likewise to secure the upper horizontal portion to the step.
