A safety line system includes support assemblies which clamp to respective reinforcement bars protruding upward beyond the top surface of a concrete beam. The support assemblies include stanchion assemblies having respective posts that may be selectively pivoted relative to the beam. The support assemblies also preferably include end anchor assemblies that are connected to respective stanchion assemblies by respective chains.
