100 Ft. Rope Horizontal Lifeline System – 4 Person

100 Ft. Rope Horizontal Lifeline System – 4 Person | 14,500 lb. Breaking Strength Fall Protection

The Palmer Safety 100 Ft. Rope Horizontal Lifeline System (SKU: A300400) is a professional-grade fall arrest solution engineered for multi-worker job sites requiring flexible, span-adjustable protection. Designed to accommodate up to four workers simultaneously, this system spans from 15 ft. to 100 ft. and is built around a 3/4" double braided polyester rope rated to a 14,500 lb. breaking strength. It is intended for contractors and trades professionals working at elevation on structures where two fixed 5,000 lb. anchor points can be established. The complete kit arrives preassembled in a backpack-style carrying bag, enabling rapid deployment, takedown, and transport between job sites.

Technical Specifications

Unlike single-worker lifeline systems, this kit is rated for up to four simultaneous users across a span of up to 100 ft., making it well-suited for larger crews working on rooftops, bridges, or structural steel. The preassembled backpack configuration eliminates on-site rigging complexity and reduces setup time compared to component-based systems sourced separately. The 3/4" double braided polyester rope construction delivers the tensile strength and abrasion resistance required for demanding commercial and industrial applications.

Key Features & Benefits

Multi-Worker Capacity

Rated for up to four workers simultaneously, this system allows an entire small crew to remain tied off to a single lifeline without requiring multiple independent anchor setups. This reduces equipment overhead and keeps crews compliant on jobs where multiple workers share the same elevated work zone.

Adjustable 15 ft. to 100 ft. Span

The system adjusts across a wide range from 15 ft. to 100 ft., giving contractors the flexibility to configure protection for varying structure widths without purchasing multiple systems. The included rope tensioner with tool allows the rope to be properly tensioned at any span within that range.

14,500 lb. Breaking Strength

The 3/4" double braided polyester rope is rated to a 14,500 lb. breaking strength, providing a substantial safety margin above the anchor point requirement of 5,000 lbs. per anchor. This high tensile rating supports the combined load demands of a four-person system under fall arrest conditions.

Preassembled Backpack Kit

The entire system arrives preassembled and packed in a dedicated carrying bag, enabling fast deployment and takedown on site. This design is particularly valuable for contractors who move between multiple job sites and need a fall protection system that can be set up and broken down efficiently.

Complete Hardware Included

The kit ships with two carabiners, a rope tensioner with tool, and two 6 ft. cross arm straps, so no additional hardware purchases are required for a standard installation. Having all components matched and included eliminates compatibility concerns that arise when assembling a system from separate components.

OSHA 1926.502 Compliance

The system meets or exceeds OSHA 1926.502, the federal standard governing fall protection systems in construction. Contractors can deploy this system with confidence that it satisfies regulatory requirements for horizontal lifeline fall arrest systems on covered job sites.

Common Applications

Rooftop Work

The adjustable span and multi-worker capacity make this system well-suited for roofing crews working across flat or low-slope commercial rooftops where two structural anchor points can be established at the roof perimeter or structural members.

Structural Steel Erection

The high breaking strength and 100 ft. maximum span allow ironworkers and structural crews to establish a continuous lifeline across steel bays, keeping multiple workers protected during erection and connection activities.

Bridge and Infrastructure Construction

The system's long span capability and durable polyester rope construction make it appropriate for bridge decks and infrastructure projects where workers must traverse extended horizontal distances at elevation.

Multi-Trade Elevated Work Platforms

On job sites where multiple trades work simultaneously at elevation, the four-person capacity allows a single lifeline installation to serve an entire small crew, reducing the number of independent anchor setups required.

Temporary Construction Structures

The preassembled backpack format and adjustable span make this system practical for temporary elevated work areas such as formwork decks or scaffolding platforms where the lifeline must be installed and removed repeatedly.
