Retrofit Stair Nosing is an answer to the hazard posed by worn or damaged stairs. Made of hard, non-slip abrasive material permanently bonded to a base of heavy-duty, extruded aluminum, the product reportedly complies with ADA, OSHA, and most all building codes and insurance requirements. Its edge fits flush on the rise with a minimum of exposed aluminum. Retrofit Stair Nosing can be installed over virtually any stair material, including concrete and terrazzo, by using stainless steel, flat-head screws and requires only routine cleaning products for maintenance.
