A carabiner is a metal loop or spine having a screw locking gate or spring gate. . The word has its origin in the German word “Karabinerhaken” which means “hook for a carbine’. Carabiners are commonly used in mountain climbing and industrial works. A number of graded carabiners are manufactured with certified safety ratings.
Carabiners that are popularly used in climbing come in the locking and non-locking varieties. Locking carbiners are installed with auto locking gates or twist lock gates to secure the gate from getting accidentally opened or unclipped. Climbers usually use locking carbiners while setting up any anchor so that the system is secure. Climbing is a dangerous activity and all steps should be taken to use the right gear to avoid any accidents.
Non-locking carabiners have a spring swinging gate that open and shut with the pressure of the spring. The gates used in a non-locking carbiner can be a straight gate, bent gate or a wire gate. It is common for climbers to connect two non-locking carabiners by using a short sling, and turning it into a quickdraw.
Different shapes of carabiners are available such as the oval carbiner which can be used for any purpose and are the cheapest. The D shaped carabiners carries most of the load on the metal loop and is a stronger variety though more expensive. The offset-D carabiners have a bigger gate opening thus facilitating easy clipping of things.

Heavier steel carabiners are generally used for industrial purposes with a screwed shut gate instead of the sprung gate commonly used in carabiners. The screwed shut gate can be operated only with a special tool to open or close it.
