Abstract
An injection molded stair nosing has a tread member, a front portion of which is downwardly and backwardly canted from the horizontal by about 5 to about 7 degrees. The front portion is supported by a plurality of spaced apart support ribs underneath the front portion. Each support rib may have a front concave surface to fit to a curved transition of a stair tread to a stair riser or nose. A back portion of the tread member is tapered to mitigate any interference with the foot or shoe of a user.
