Description
The 3M™ DBI-SALA® Nano-Lok™ Self-Retracting Lifeline (SRL) – 3101603 is a compact and versatile fall protection solution engineered for working at heights. With an extended 9 ft (2.7 m) lifeline, this model is ideal for environments requiring both mobility and fall arrest performance. The SRL features a durable thermoplastic housing and an abrasion-resistant web lifeline, ensuring rugged performance across industrial applications. Designed with a self-locking snap hook on the lifeline end and a carabiner anchorage connection, it is quick to install and compatible with a wide range of harness configurations. Certified to CSA Z259.2.2-17 (Class SRL), this lifeline ensures consistent protection and peace of mind in both construction and general industry settings.
Key Features
Extended 9 ft (2.7 m) Web Lifeline: Provides increased working range over traditional lanyards while maintaining lightweight maneuverability.
Durable Thermoplastic Housing: Designed to withstand tough jobsite conditions and daily wear.
Self-Locking Snap Hook: Secure and easy-to-use connector on the lifeline end for fast attachment to harness D-rings.
Anchorage Carabiner Included: Allows secure attachment to anchor points, scaffolding, or structural connection hardware.
Internal Energy Absorber: Reduces fall forces to protect the worker in the event of a fall.
Quick-Activating Brake System: Stops falls within inches to limit free fall distance.
Intended Use
Ideal for workers in construction, general industry, and elevated maintenance tasks, the Nano-Lok™ 3101603 is engineered for users who need a compact, fast-activating SRL with extended range. The 9 ft web lifeline is especially beneficial when working on platforms, scaffolds, or structures where mobility is essential but fall clearance is limited.
