Carabiners rated for climbing have minimum strength requirements to ensure the gear will not break when used properly. Climbing carabiners are rated in 3 orientations.
Major Axis
This is the strongest orientation and the way carabiners are designed to be loaded.
Open Gate
While climbing, carabiners lying against the rock can be opened slightly as they move across an uneven surface. A carabiner can also open slightly during a fall as the ‘biner starts to vibrate, dispersing the energy (also called “gate flutter“). A weak gate closure (due to a poor/failing spring or an over-stressed wire) could also leave the gate ajar.
Minor Axis
Carabiners are not intended to be loaded along the minor axis (cross-loaded), but it’s possible for a carabiner to unintentionally rotate during use, particularly during a belay. Of all accidental misuses of a carabiner, cross-loading is the most frequent suspect, which is why there is a rating for it.
When oriented in this way, wire gates are generally stronger than solid gates. A wire gate bends during the test, absorbing some of the force, compared to a solid gate that is less pliable.
