Patent abstract

A stringer assembly includes a support element, a plurality of brackets and a plurality of alignment elements. The brackets are connected to the support element, and each bracket includes a rise indicator corresponding to a desired rise dimension and a run indicator corresponding to a desired run dimension. The alignment elements align the rise or run indicator on one of the brackets with the other of the rise or run indicator on an adjacent one of the brackets to space the brackets at a desired rise and run. The brackets each include a tread flange and a riser flange, such that a tread and a riser can be directly connected to each bracket. The brackets may include cutouts for a temporary tread system.
