Abstract
A safety barrier is provided for transports such as moving walks or stairs (escalators) which have a moving surface and fixed sidewalls. The barrier is a strip barrier brush assembly adapted to be attached to the sidewall and includes at least one brush strip adapted to project over the edge of the moving surface. The assembly includes a rail housing having a channel slot extending parallel to the direction of movement of the surface. The rail housing includes a hollow upper or lower portion including a rearward surface and a spaced outer surface. A through hole is formed through such surfaces by a smaller opening in the rearward surface and a larger opening in the spaced outer surface so that the rearward surface forms a fastener retention surface with access there to being obtained through the larger opening. The larger opening may be closed by a flush through hole cap.
