What are different biners used for?
Without a doubt, carabiners (biners for short) are the most widely used piece of climbing gear. Whenever you have a roped system in climbing, the chances are nearly 100% that theres at least one carabiner involved, usually more. But while theyre so widely used, theyre also very specialized. Theyre really only made to pulled along their major axis, and when you do anything else to them, they become substantially weaker. There are a few main types of biners and several SEVERAL sub categories. Were not going to get into the sub categories here.
