3M 3100261 Self-retracting Lifeline 20 Ft Class 1

Product Description

The 3M 3100261 is a self-retracting lifeline (SRL) from the DBI-SALA Nano-Lok XL series, designed for fall protection in industrial and construction environments. The unit features a Dyneema webbing lifeline for high strength at low weight, paired with a galvanized steel locking snap hook at the connection point. A swivel hook attachment reduces lifeline twisting during movement. At 6.72 pounds, the 3100261 is built for single-leg use and is classified as a Class 1 SRL per ANSI standards, making it suitable for applications where the arrest force must be strictly controlled.

This self-retracting lifeline is intended for use by workers requiring overhead or near-overhead anchorage fall protection. The 20-foot lifeline length accommodates a range of working distances from the anchorage point. Single-leg configuration makes it appropriate for general work positioning on structures, rooftops, elevated platforms, and similar job sites. It is installed and inspected by qualified safety professionals or competent persons as defined under applicable OSHA regulations.
