Adding a Self-Retracting Lifeline (SRL) with retrieval capability provides fall protection as well as rescue capability. The arm shown above mounts using a portable base designed to clamp onto or into existing access ways. Exclusive TUFF-KLIK connectors Eliminate adjustment pins that can be easily damaged or lost and allow for easy incremental set up and adjustment of the structure.
