Carabiners are widely used in sports requiring ropework, such as climbing, caving ("Single Rope Technique"), canyoning, and sailing, and in industrial rope access work, such as construction or window cleaning.
The carabiner is the link between a rock climber and their protective hardware, rope, and accessories. It is a reusable aluminum alloy ¡§hook¡¨ featuring a spring-loaded gate that opens inward and automatically snaps closed when released. Most high-quality carabiners designed for recreational use are made from aluminum alloy, which offers an excellent strength-to-weight ratio.
