ABSTRACT:
An improved stair nosing device especially useful in temporarily darkened stairways is provided which includes a plate member with an upper surface, at least a portion of which is covered by luminescent material. The stair nosing device includes non-slip material attached to the upper surface to provide increased frictional contact with foot traffic relative to the plate member. The non-slip material is attached as spaced apart strips with an upper surface of the non-slip material being higher relative to the plate member. In this way the luminescent material is protected from damage by foot traffic.
