Abstract
A stair nosing is constituted by a flat frame for lying on a tread of a stair, a non-skid flat tire-like sheet adapted to be snappedly engaged to the flat frame and a tongue-shaped protector for the engaging portion of the flat sheet frame and the non-skid flat sheet. The non-skid flat sheet includes a connecting plate of rigid synthetic resin having a flange with a rib at one edge and a non-skid flat tread of flexible synthetic resin integrally formed on the upper surface of the connecting plate. The tongue-shaped protector is integrally formed with the non-skid flat tread so as to cover the engaging portion of the frame sheet and be spaced from a riser of the stair when the non-skid flat sheet is secured to the flat sheet frame.
