- Carabiners are widely used in rope-intensive activities such as climbing, sailing, hot air ballooning, rope rescue, construction sites, window cleaning, whitewater rescue, etc.
- They are made from both steel and aluminum.
- Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue.
- There are three broad categories of locking mechanisms for carabiners: auto-locking, manual locking, and non-locking.
- Locking carabiners have the same general shape as non-locking carabiners but have an additional mechanism securing the gate. These mechanisms may be either threaded sleeves (“screw-lock”), spring-loaded sleeves (“twist-lock”).
