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.
