3M 3100618 Self-retracting Lifeline Quick Connect 8 Feet

Product Description

The 3M 3100618 is a self-retracting lifeline (SRL) designed for fall protection in overhead and at-height work applications. Sold as the Nano-Loka Wrap Back SRL, it functions as both a fall arrest device and a tie-off adapter. The unit ships with a built-in quick-connect pin-style connector for direct harness attachment, eliminating the need for a separate snap hook at the dorsal ring. The lifeline is constructed from Dyneema webbing, known for high strength-to-weight ratio. The housing is thermoplastic. Total unit weight is 8.36 pounds. A licensed safety professional or competent person, as defined under OSHA 29 CFR 1926 Subpart M, should verify the anchor point and system before use.

This SRL is intended for use in residential and commercial construction, steel erection, concrete forming, and general industry overhead anchor applications. The wrap-back design allows the unit to be tied off directly to structural steel, rebar, walls, and other structures capable of supporting fall arrest forces, making it adaptable across multiple jobsite configurations. It is sold individually (each).

Key Features

• Wrap-back design functions as both SRL and tie-off adapter for direct attachment to structural steel, rebar, or walls
• Dyneema web lifeline provides high tensile strength in a compact form factor
• Quick-activating speed-sensing brake system engages automatically during a fall event
• Built-in pin-style connector allows direct attachment to harness dorsal ring without an additional connector
• Durable thermoplastic housing resists jobsite wear

Compatibility

Designed for use with full-body fall protection harnesses equipped with a standard dorsal D-ring connection point. Verify harness and anchor compatibility with the system before installation. Consult 3M documentation for approved anchor configurations.

Installation Notes

Installation and inspection must be performed by a competent person as defined under applicable fall protection regulations, including OSHA 29 CFR 1926 Subpart M for construction or 29 CFR 1910 Subpart D for general industry. The anchor point must be capable of supporting the required fall arrest load before attaching the SRL. Inspect the lifeline, housing, and connector for damage before each use and remove the unit from service if any defect is found. Do not modify, disassemble, or repair the unit in the field.
