Kee Line® Case Studies

    Frequently Asked Questions

      • How is this horizontal lifeline better than other systems?
        The Kee Line Horizontal Lifeline system is technically superior since it's engineered to immediately absorb energy to minimize impact. The energy absorber is calibrated to impart lower forces into the system in a minor fall. In the event of a more severe fall, the forces are ramped up gradually, providing more stopping power.
      • Is the Kee Line price competitive to other horizontal lifeline systems?
        Yes. The Kee Line Horizontal Lifeline system, when backed by the Kee Line Calculator, immediately provides a materials list so you have an optimized system with in-stock components that is easy to install. This saves you time, money and less labor costs on-site. All components are ISO 9001 assured and made from galvanized, corrosion-resistant steel for long life on the roof.
      • Are the Kee Line components in stock?
        We offer low lead-times for increased productivity. Kee Line inventory is always in-stock, which means prompt delivery and no down time waiting for materials so you can get the installation completed quickly.
      • What does the Kee Line Calculator do for installers?
        The Kee Line Calculator provides both installer and customer with the safest system in the field. It also provides a complete list of components for the entire installation. The calculator does all the math for you and provides alerts if there are any improper calculations. This eliminates risk. Finally, the calculator ensures the HLL system is compliant with OSHA and ANSI regulations and is part of a complete personal fall arrest system that maintains a safety factor of at least two.
