Can you hook two carabiners together?
We don’t see any issue with connecting a carabiner to a carabiner as long as two conditions are met. The carabiners should be “floating,” meaning they are not able to come into contact with a hard surface and are free to rotate if necessary. That will prevent damage due to torque loading.

When should I retire a carabiner?

How do you tell if a climbing rope is safe?
One way to inspect the integrity of the core is the pinch check. Pinch two nearby parts of your rope together. If the rope flattens to the point where the two strands are parallel, your rope is core-shot. This means the core of the rope is no longer strong enough to safely catch falls and should be retired.
How long do climbing carabiners last?
A carabiner can last much longer than most climbers usually keep them (well over 15 years). Often new gear is so enticing that many climbers choose to retire their older carabiners before it’s absolutely necessary. On the other hand, lack of care can result in a carabiner needing retirement in less than 5 years.

How many falls can a climbing rope take?
