The lifelines remain under tension during normal movement, helping reduce slack, dragging, and potential trip hazards. A high-capacity external energy absorber and impact indicator provide additional fall-arrest protection and inspection visibility.
The twin-leg configuration is particularly useful when workers need to move around structures while maintaining 100% tie-off. The aluminum rebar lock hooks provide a large attachment opening suited to compatible structural anchorage points and reinforcing steel applications.
