The Guardian CR3-Edge Cable Self-Retracting Lifeline (SRL), featuring integrated digital inspection and asset management powered by Twiceme Technology, represents one of the most advanced and essential pieces of fall protection equipment.
The CR3-Edge is engineered for demanding jobsite conditions and is ideal for steel, concrete, and B-decking applications. Its lightweight thermoplastic housing provides durability while maintaining ease of use for workers operating at height.
With embedded Twiceme Technology, users can streamline digital inspections to ensure PPE is in good working condition, track on-site certifications, and easily manage inventory and assets via the Twiceme app's Equipment Health Inspection and Work Document features. Users tap the NFC-enabled equipment with a smartphone to log findings, flag issues, and instantly sync records to Twiceme’s safety management portal and app. Equipment inspections are timestamped and signed off, eliminating paper logs and giving safety teams complete visibility into equipment compliance status
It also includes the Medical ID features to assist first responders in rescue missions — a critical safety feature for those working at heights over six feet, where the risk of a serious fall increases dramatically.
Designed as a Class 2 SRL for leading-edge environments, the CR3-Edge combines reliable fall protection with modern equipment management capabilities. The SRL is also designed for use in lifts and mobile elevated work platforms (MEWPs) where overhead anchorage is unavailable. In these applications, the housing-side carabiner attaches to the lift’s designated anchor point, while the snap hook connects to the dorsal D-ring of the worker’s harness. Because lifts and MEWPs do not provide overhead anchorage, a Class 2 or leading-edge-rated SRL is required. With 10 feet of usable cable, workers can move freely throughout lifts.
