Abstract
A bracket for use in manufacturing a step supported by a stringer. The bracket includes an anchor block to which a tread for a step may be attached, a pair of frames flanking the anchor block and fixed thereto, and markings formed on at least one of the frames. The markings indicate a rise and a run for the step. The bracket may be used in a method for building a stairs. The method includes the steps of selecting a desired tread distance and rise distance for the stairs to be built, fastening tread receiving portions and riser-receiving portions of a bracket to a first elongate stringer to define the desired tread and riser distances, repeating the above steps with respect to a second stringer, mounting a tread to the tread-receiving portions, and mounting a riser to the riser-receiving portions.
