A stairway system is disclosed that includes a plurality of spaced apart treads; a handrail; and at least two balusters per tread. Each baluster includes a top length segment, a bottom length segment and a turning length segment, the turning length segment including a portion of defined features. According to the present invention, a length of the turning length segment of a subsequent baluster is greater than a length of the turning length segment of a previous baluster on the same tread according to the equation of the riser height divided by the total number of balusters. Thus, each of a portion of the defined feature in the bottom length segment of each of the balusters align with the tread for each baluster. In the preferred embodiment, only four different baluster lengths are necessary for both two and three balusters per tread stairway systems.
A kit of materials for assemblage into a handrail assembly for attachment to a stairway having treads at a riser height of 7½ inches, the kit of materials for selectively constructing a handrail assembly comprising between two and three balusters per stairway tread wherein the balusters are evenly spaced and include top and bottom features and the bottom features of the balusters align parallel to the tread surface while the top features of the balusters align parallel to the handrail of the handrail assembly and comprising:
