CARABINERS

Carabiners are widely used in sports requiring ropework, such as ziplining, rock climbing, slacklining, caving, canyoning, and sailing, and in industrial rope access work, such as construction or window cleaning.  Carabiners used in sports tend to be lighter than carabiners used in industry. For recreational climbing, almost all carabiners are made from 7075 aluminum and are treated to a T6 temper (solution treated and then artificially aged). For zip lining, rope rescues, and industrial carabiner uses, where the weight of the carabiner is not an important factor and larger working loads are encountered, steel carabiners are commonly used.
