Self-Retracting Lifelines (SRLs) & Inertia Reels

When every second counts, a Self-Retracting Lifeline (SRL)—also commonly known as an Inertia Reel—provides one of the safest and most effective methods of fall protection for workers operating at height. Designed to extend and retract automatically as you move, inertia reels keep the lifeline under constant tension, reducing slack, minimising trip hazards and significantly decreasing free-fall distance. In the event of a fall, the internal braking mechanism locks instantly to arrest the fall and reduce impact forces, much like a vehicle seatbelt.
