MSA Self Retracting Lifelines

The MSA Dyna-Lock Self Retracting Lanyards (SRL) are fast-acting fall arresters that limit free-fall distance, deceleration distance and fall arrest forces while allowing user freedom of movement. The Dyna-Lock SRL is ideal for climbing applications where vertical mobility is needed.

The Dyna-Lock SRL has a 4.5 feet per second locking speed. A built-in shock absorber limits fall arrest forces to under 900 lbf. Three continuously moving independent braking mechanisms prevent freezing in icy or corrosive conditions. Available with 3/16 inch galvanized or stainless steel wire rope, or 1 inch wide nylon webbing. A forged steel, zinc-plated, self-locking swivel snaphook is present on each unit with a load indicator that activates and alerts the user when the Dyna-Lock SRL has been impact loaded. The Roughneck model incorporates a black corrosion-resistant coating designed for severe environmental conditions. Meets ANSI Z359.1, ANSI A10.14, and applicable OSHA standards. Models with CSA part numbers are CSA certified.
