A Retractable Fall Arrester Block, also known as a Self-Retracting Lifeline (SRL), is a vertical lifeline used as part of a complete fall arrest system. It functions similarly to a seatbelt, where the lifeline extends and retracts smoothly but locks when a sudden force, such as a fall, is applied. The internal braking mechanism disperses the energy of the fall, limiting the impact on the user.
