Meeting standards. Elevating expectations.

The 3M™ Protecta® Self-Retracting Lifeline (SRL) is an affordable fall prevention solution without sacrificing effectiveness or safety. It is strong yet lightweight and engineered to last. This SRL is developed with the worker in mind, with a stackable housing design, web or steel cable lifeline, and a built-in swiveling anchorage point for extra comfort and convenience. 3M™ Protecta® Self-Retracting Lifelines are available in multiple lifeline lengths as well as SRL, personal SRL, Leading Edge SRL, and Retrieval SRL configurations.

As the worker performs their various tasks, the 3M™ Protecta® Self-Retracting Lifeline (SRL) extends and retracts with them. The lifeline's constant tension prevents slack which can cause dragging, snapping, and trip falls. Should a fall occur, a speed sensing brake system activates, stopping the fall and reducing the forces imposed on the user to safe levels.

Whether your application calls for single or twin-leg configurations, mounting to an overhead anchor, or connecting directly to a harness, there are a variety of fall protection models to accommodate almost any application. These features are significant advancements in terms of safety and offer the user increased protection while on the job.

Product Highlights

  • Corrosion-resistant components with an aluminum stackable housing design
  • Swiveling anchorage connector loop and carabiner
  • Self-locking snap hook on lifeline
  • Quick activating speed-sensing locking system
  • Features impact-indicating external energy absorber (for models with external shock pack)
  • Reliable fall arrest energy dissipation system
