Adjustable lifeline with energy absorber via the buckle sliding and the controlled stretching of the belt up to 8%.
This kinetics has two functions:
1. The lifeline anchorage points aren't deformed or broken so that the anchorage isn't released.
2. Snatch to the body is absorbed is order to allow the lifeline to work properly. The space between anchorage and buckle should be at least 1 m.
