Multi Span Lifeline Systems are versatile, economical solutions that equip rooftop workers with continuous, active fall protection. A single horizontal lifeline allows up to three workers to perform their tasks with complete fall protection. Because workers are continually attached to the safety line, Multi Span Lifelines make it possible for workers to safely access all areas of a rooftop. Multi Span Lifelines has been third-party tested. They meet both OSHA and ANSI requirements as well as standards set by CSA 13-04 & 16-04.
