- 摘要：
- Laminate covered stair nosing is affixed with sheet metal prongs, extending at right angles from the top surface of a sheet metal fastener, on the leading edge of a stair step. The sheet metal fastener has a U shaped flange extending beyond the leading edge of the tread. The laminate covered stair nosing has a planar top surface and a planar bottom surface. Prongs on the sheet metal fastener are forced into the planar bottom surface for affixing the stair nosing on the tread. The stair nosing has a U-shaped leading edge. The U-shaped leading edge extends beyond the leading edge of the tread. The U-shaped flange on the sheet metal fastener is interlocked with a channel in the U-shaped leading edge for supporting the stair nosing on the tread. A shoulder on the stair nosing abuts with the front surface of laminate flooring on the riser for retaining laminate flooring installed over a pad on the riser of the stair step.
