Center is a standard carabiner rating. Using a carabiner to connect to a rope. A carabiner or karabiner (/ ˌ k ær ə ˈ b iː n ər /), [1] often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate [2] used to quickly and reversibly connect components, most notably in safety-critical systems.
It is also considered a useful tool in many types of rope rescue, such as crevasse rescue, because of its simplicity, and is commonly used for lifting systems that don't require much more mechanical advantage. [5] It also serves as a method for tightening the rope in a Tyrolean traverse, where the other end is fixed to a stable object.
The mechanical advantage is 2, requiring a force of only 50 N to lift the load. A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a ...
The friction of the rope against the screw on the carabiner can cause the screw to undo and the carabiner to open, potentially weakening the strength of the carabiner, or allowing the rope to escape the carabiner completely. Therefore the hitch has to be tied correctly with the braking end on the opposite side of the carabiner than the gate is.

Non-locking (top) and locking (bottom) carabiners. Carabiners are closed metal clips with spring-loaded gates that are used as connectors between the rope and various devices. Modern carabiners are made from a lightweight but strong aluminum alloy that can withstand the load of a fall. Carabiners come in various shapes, with the asymmetric ...
