CARABINERS

Zipline carabiners are widely used in sports requiring ropework, such as ziplining, rock climbing, slacklining, caving, canyoning, and sailing, and in zipline rope access work, such as tower construction or stringing ziplines. Carabiners used in sports climbing tend to be lighter than carabiners used in the zipline industry. For Ziplining and recreational climbing the needs are not always the same. Almost all aluminum 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. Steel carabiners are used when clipping to a cable or steel support.
