The MSA Dyna-Lock self-retracting lanyard is a fast-acting fall arrester that limits free-fall distance, deceleration distance and fall arrest forces while allowing the user freedom of movement. The Dyna-Lock self-retracting lanyard is ideal for climbing applications where vertical mobility is needed. The Dyna-Lock self-retracting lanyard has a 4.5 feet per second locking speed. A built-in shock absorber limits fall arrest forces to under 900 lbs. Three continuously moving independent braking mechanisms prevent freezing in icy or corrosive conditions. A forged steel, zinc-plated, self-locking swivel snap hook is present with a load indicator that activates and alerts the user when the SRL has been impact-loaded. No factory re-certification required. Meets ANSI A10.14, ANSI Z359.1 and applicable OSHA standards. CSA certified.
