Just follow three steps show as the picture above, you will find it is so easy to use. Aluminum  is the most common material for carabiners used in rock climbing.  Aluminum is light and stiff,making it ideal for a climber&#039;s harness  since extra weight can put a serious drag on a climb, especially in  remote areas. A high-quality  aluminum carabiner usually has a high strength rating compared to other  climbing equipment like harnesses and rope. You&#039;ll be safe using an  aluminum carabiner in almost all applications. For  rock climbers, carabiners are a quintessential and safety piece of  equipment., which should be treated with care and respect. A  drop of greater than five feet can compromise the strength of a steel  or aluminum carabiner, limiting its safety. Don&#039;t share carabiners with  others,since you cannot ensure their carabiners have not been dropped. In  addition, check the locks and gates on all of your carabiners before  using them as part of a suspension system,and always secure carabiners  with the open side of the gate pointing down to discourage the locks  from unscrewing during your climb.
