The lower side of the guide rail below the opening is inclined outwardly and serves to contain foreign matter present within the guide rail as well as to catch matter falling from above. The hangers each include a projection adjacent the longitudinal opening which serves to prevent the splashing of foreign matter from the interior of the guide rail out through the opening.
