DBI/Sala® Ultra-Lok™ Self-Retracting Lifelines-SSAC, with an extremely lightweight thermoplastic housing, are super rugged and superbly engineered devices you can count on for safety, efficiency and comfort. Stainless steel components, an anti-ratcheting brake system and a semi-sealed design provide the user with a system built to last. These SRLs are backed by decades of proven field service for absolute confidence, safety and reliability. An SRL’s lifeline will extend as the user moves away, and will retract automatically enabling the user to move about within a recommended working area at normal speeds. Should a fall occur, a speed sensing brake system will activate to stop the fall and reduce the forces imposed on the user to safe levels. DBI/Sala’s Ultra-Lok Self-Retracting Lifeline-SSAC also features a 3/16" (5mm) stainless steel cable lifeline in various lengths, an internal energy absorption system, an anti-ratcheting twin disk brake system, constant moving brake system pawls, a swiveling anchorage point, a swiveling snap hook with an impact indicator, a reserve lifeline system, and an ergonomic cable handle equipped with i-Safe™.
