摘要: A temporary rooftop and stairway safety rail system (16a & 16b) adapted to prevent workers from falling from a work surface at a height. The system includes a plurality of safety rail support assemblies (16) having a vertical support member (52) with members for retaining horizontally disposed safety rail boards (58). The safety rail support assemblies (16) may be mounted on walls (22) and roof rafters (18), and the pitch of the vertical support members is easily adjusted to the slope of the work surface using a system of removable pins (32).
