ABSTRACT:
A stair building template comprises a plurality of rectangular-shaped horizontal members and a plurality of rectangular-shaped vertical members. Connectors are provided which each hold a horizontal member in a right-angled relationship with a vertical member and each vertical and horizontal member is associated with at least one connector. The horizontal and vertical members slide along their mutual connector when the connector is loosened, but are held fixed with respect to each other when the connector is tightened. Manipulation of the connectors permits the framing of the horizontal and vertical members into a configuration with the desired dimensions for the proposed staircase.
