- Self-locking carabiner
40mm automatic ZICRAL aluminium carabiners: the autolock moves up for an easier and wider opening.
- Load rating
Automatic aluminium carabiners have a limited lifetime due to metal fatigue. They must be replaced after 5 years or 500 flight hours, whichever is soonest. They should never be used between spreaders and tandem wing risers as main carabiners. They should also never be used to connect rescue systems.
