Working at height often requires mobility along a horizontal plane. A Horizontal Lifeline (HLL) is a critical component of a Personal Fall Arrest System (PFAS) that provides a continuous anchorage point, allowing workers to move safely across roofs, beams, railcars, and other elevated structures without disconnecting.
At Industrial Ladder & Supply, we offer a selection of reliable Horizontal Lifeline systems and components designed to keep your crew safe and compliant while maintaining necessary mobility on the job. Don't compromise on fall protection – choose engineered solutions you can trust.

Choosing the right HLL system requires careful evaluation based on your specific needs and work environment:
Application:
User Capacity:
Span Length & Configuration:
Required Anchorage Strength:
Energy Absorber: Does the system include one? Is one required for your application and anchors? (Most modern systems do require one).
Fall Clearance: CRITICAL SAFETY CALCULATION! The distance required below the working surface to safely arrest a fall. This calculation is complex and depends on the system length, sag, energy absorber deployment, lanyard length, and height of the worker. You must have sufficient clearance.
Material: Steel (durability, permanent) vs. Synthetic (portability, temporary).
Environment: Consider corrosion resistance for outdoor or harsh conditions.
Installation Requirements: Does it require special tools or expertise?
Horizontal Lifelines FAQs
What is the primary purpose of a Horizontal Lifeline?
To provide a continuous anchorage point along a horizontal path, allowing workers to move and maintain 100% tie-off while working at height.
What is the difference between a temporary and a permanent HLL?
Temporary HLLs are typically portable, use synthetic rope/webbing, and are designed for short-term jobs. Permanent HLLs use steel cable, require fixed anchors, and are installed for long-term use on structures.
Why is an Energy Absorber important in an HLL system?
An energy absorber reduces the forces generated during a fall. Without it, the impact force on the anchor points, the structure, and the worker could be dangerously high, potentially causing structural failure or severe injury. Most HLLs require one.
What is "Fall Clearance" and why do I need to calculate it?
Fall Clearance is the minimum vertical distance required below the work surface to safely arrest a fall. It includes the length of your lanyard, the distance the energy absorber deploys, the sag in the horizontal lifeline, and a safety factor/height of the worker. Calculating and ensuring sufficient fall clearance is absolutely critical for preventing a worker from hitting the lower level or obstructions during a fall.
How many workers can use a Horizontal Lifeline?
This varies significantly by the specific system and its design. Always check the product specifications or manufacturer's instructions for the maximum number of users allowed on that particular HLL at any given time.
Can I use any cable or rope with anchors as a Horizontal Lifeline?
Absolutely NOT. Horizontal Lifelines are engineered systems. Using non-engineered components or improperly installed systems can lead to catastrophic failure. Always use complete, certified systems and components as specified by the manufacturer and relevant safety standards.
Do I need special training to use or install an HLL?
Yes. OSHA and ANSI standards require that HLLs be designed and installed under the supervision of a Qualified Person and used under the supervision of a Competent Person. Proper training on system limitations, fall clearance calculations, inspection, and proper use is essential.
What kind of anchor points are required for an HLL?
Anchor points must be capable of supporting the anticipated forces generated by a fall on the HLL system. This often means anchors rated for 5,000 lbs per attached worker or as specified by the engineered system's design and forces (which can be much higher). The structure itself must also support these forces.
Where can I find other Fall Protection equipment like harnesses or lanyards?
This page is specifically for Horizontal Lifelines. You can find other essential fall protection gear, such as safety harnesses, lanyards, and connectors, in our main [Link to main Fall Protection Category - e.g., https://industrialladder.com/fall-protection/] or relevant subcategories.
