First system:
Use a screw-lock karabiner with a breaking strength of at least 2,400 kg. In this case, the bridles should be held in position within the karabiner
using elastic bands, to prevent the karabiner from rotating and taking the strain laterally instead of vertically. The karabiner’s screw-lock
should be tightly screwed shut to avoid any possibility of it opening accidentally. This type of connection can absorb a higher opening shock
than the second system, and for this reason this is without doubt the recommended system.
Second system:
The harness bridle should pass through the emergency parachute bridle loop. Next, the emergency parachute should be passed through the
large loop of the harness bridle. The result is a connection that should be tightened as much as possible so as to prevent dangerous friction
between the two cables during emergency opening shock. To prevent the union of the two cables from loosening over time, remember to lock
the knot with the special Velcro strip, which has already been placed on the harness bridle.
