Locking carabiners are specialized clips used in climbing, hiking, and various outdoor activities. They feature a locking mechanism that prevents accidental opening, ensuring safety when securing gear or connecting ropes. These carabiners come in different shapes and sizes, each designed for specific uses, such as sport climbing or caving. Typically made from lightweight materials like aluminum or steel, locking carabiners are durable and strong. They often have a screw-lock or twist-lock feature, which requires intentional action to open. This added security makes them essential for activities where safety is a priority, such as rock climbing or mountaineering.
