The MSA V-SHOCK EDGE Leading Edge Self-Retracting Lifeline (SRL-LE) is designed for demanding work-at-height applications where leading edge exposure is present. This single-leg SRL features a durable galvanized steel lifeline engineered to resist abrasion and sharp edges commonly found on construction and industrial structures. The compact nylon housing helps protect internal components while maintaining a lightweight, durable design suitable for daily use. Equipped with a steel triple-action carabiner for anchorage connection and a 36CS small steel snaphook with swivel for harness attachment, the device provides secure connections and smooth operation. The replaceable steel lifeline and integrated RFID identification support efficient equipment inspection and asset management programs in professional safety environments.
