ABSTRACT:
The specification discloses a template for routing stair stringers. The template includes (1) a body having opposite faces and defining tread and riser routing slots and (2) structure for registering the template body on a stringer to provide a fixed tread depth and an adjustable riser height. Preferably, at least a portion of the registration structure is transversely shiftable within the template body to provide an unobstructed routing face regardless of which template face is laid against the stringer.
