Cable Based Horizontal Lifeline Systems

FLS Cable based horizontal lifeline systems are a versatile fall protection solution that provides a safe means of tie off for workers in a variety of applications. With spans up to 180’ and supporting multiple users, FLS Cable lifelines provide an economical and efficient solution for workers at height.

Whether designed for an overhead application, such as an aircraft hangar, or at foot level on a roof, a properly engineered FLS Cable lifeline ensures the safety of employees and workers exposed to falls.

Cable Based Fall Safety System

Pass Thru Capability

FLS Cable trolleys and shuttles on all cable based lifelines feature pass thru capability of intermediate support points. Eliminating the need to use double lanyards or disconnect from the lifeline reduces risk and improves user efficiency.


All Flexible Lifeline Systems are available in 316 stainless steel cable and components, ensuring they will last for 20+ years.

Cable versus Rigid Rail

There has been much debate about which is better, cable or rigid rail horizontal lifelines. When designed correctly, both cable and rigid rail lifelines offer excellent levels of fall protection. Rigid rail systems have the advantage of lower fall distances and are often preferred when work is performed less than 12’ above a lower level. Cable based lifelines have the advantage of practicality in scenarios where a rigid rail system is less feasible, such as on roofs, arena rigging grids and along overhead crane rails.

Cable Horizontal Lifeline Case Studies

Overhead Lifeline for Southwest Airlines

The Southwest Airlines maintenance team required the capability to add two 737-900 aircraft near the front of one of their hangars requiring the engineering of atypical support connections for the system anchor points.

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.

Kokea Construction Case Study

The project consisted of providing five new horizontal lifeline systems to provide workers an overhead tie-off while working on the rigging grid.

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.

Evonik Overhead Lifeline Case Study

An overhead fall protection system was needed in their Acrylic Bay to access the tops of trucks loading materials for distribution.

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).

Encore Wire Overhead Lifeline Case Study

Flexible Lifeline Systems designed, engineered, and installed one 140′ Overhead Horizontal Lifeline on gallows. Encore Wire installed foundations based on Flexible Lifeline Systems’ design and anchor bolts.

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.

Katoen Natie Overhead Lifeline System Case Study

FLS designed, fabricated, and installed gallows with connected overhead horizontal lifeline systems. These systems allow Katoen employees to safely access the tops of bulk railcars.

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.
