Horizontal Lifeline Systems for Fall Safety

Flexible Lifeline Systems has designed and installed Multi Span Lifelines to provide safe and effective fall protection in a variety of applications for over 20 years. On average, we design, supply and install over 9 miles of cable based lifelines every year.

Proprietary Optimized Systems

Multi Span lifelines typically consist of a 316SS 8mm cable supported every 30’, with overall lengths up to 500’ or more. Integrated energy absorbers, turnbuckles and tension indicators manage loads imparted to the supporting structure and the users. Our proprietary software analyzes the dynamic forces of each system to provide predictable and real world results to ensure worker safety in the event of a fall.

Multi Span Fall Protection on Rooftop

Continuous Fall Protection

Multi Span Horizontal Lifeline Systems feature intermediate supports and cable shuttles allowing users to pass thru without disconnecting from the lifeline, ensuring 100% tie-off.

Multi Span Horizontal Lifeline Systems are used in a variety of industries and applications including; roofs, overhead cranes, pipe racks, railcars, water treatment facilities, arena rigging grids and many more.


Takata Case Study

FLS installed approximately 900 total feet of FlexGuard Permanent Guardrail on various areas of the main building roof. Most notably, the area around the rooftop access hatch was able to be protected by FlexGuard Permanent, due to the versatility and adjustability of the product.

Lubrizol Case Study

Flexible Lifeline Systems designed, installed, and engineered an 85 feet long Multi Span Lifeline System with eight redirect anchors.

Chamberlin Case Study

Flexible Lifeline Systems designed, supplied, and installed 32 Tieback Anchors, one 280 feet Multi Span Lifeline System, and one FlexGuard Portable safety railing.

Texas State University Case Study

Flexible Lifeline Systems’ scope of work included the design, supply, and installation of four Horizontal Lifeline systems. Two systems were positioned on Roof A and two systems on Roof B starting from the hatch and running the parameter of the rooftoop.

UTSA Case Study

The FLS design included a structural analysis of the new building and a rigorous approval process to prove that the FLS system was a substantial improvement over the system originally specified for rooftop fall safety.

Altech Case Study

Horizontal Lifelines and single point anchors were needed on multiple rooftops to allow safe access to the roof for maintenance.

Olam Edible Nuts Case Study

FLS designed three Multi-Span Lifeline Systems (33’, 113’ and 210’) to access the roof on 2 buildings at the Brooks Peanut Co. shelling factory (a subsidiary of Olam Edible Nuts).

Chait & Company Case Study

FLS designed, supplied, and installed thirty-four (34) membrane posts (PN LAKL2POST) to the roof deck using toggle bolts (PN LAKL2TOGA) to make a single 1250 ft. Multi-Span Lifeline System.

Orion Construction/Juneau Federal Building Case Study

The General Services Administration requested the installation of a new fall protection system that replaced the existing non-engineered system located on the main roof level and to add a new system on the upper roof level.

Horizon Group/Houston Community College Case Study

Flexible Lifeline engineers reviewed construction plans and assessed potential hazards. FLS designed, supplied, and installed a Multi-Span Lifeline System totaling about 480ft, located approximately 10ft along the rooftop’s leading edge.

George Steel/Caresource Office Building Case Study

FLS Engineers provided an OSHA compliant system that includes horizontal lifeline systems along with strategically placed tieback anchors to accommodate window washing personnel.
