MOS Reference: ANSI Z359.13 compliant shock-absorbing lanyard limiting maximum arrest force to 900 lbs (4 kN) to reduce injury risk during a fall. Internal energy-absorbing pack deploys progressively to decelerate the fall over a controlled distance. Dual-leg Y-configuration allows 100% tie-off when traversing between anchor points (single-leg also available). Snap hooks at all connection points feature self-closing, self-locking gates to prevent rollout. Total deployed length including deceleration distance must be factored into free-fall clearance calculations. Rated for users up to 310 lbs (140 kg).
