Permanent horizontal fall arrest/restraint solution designed to protect workers during maintenance, inspection and cleaning of industrial and residential roofs. The Scope Multi® roof line system is different from any other solution available. The Instant Energy Absorbing post deforms immediately in the event of a fall, absorbs the energy created and limits the force on the structure and the user, keeping both safe at all times. This special post also provides the possibility of designing systems with longer distances in between intermediate supports reducing the overall cost of material and installation of a project. The system is suitable for up to 4 simultaneous users and has a sliding element (Scope Multi® Shuttle) that provides freedom of movement over the system without disconnected.
