Non-locking carabiners are versatile metal clips used in various activities, such as climbing, camping, and securing gear. Unlike locking carabiners, they do not have a mechanism to prevent accidental opening, making them quicker to use. They are typically lighter and easier to handle, which can be beneficial in situations where speed is essential. These carabiners come in different shapes and sizes, often made from materials like aluminum or steel. While they are suitable for many applications, they are not recommended for safety-critical uses, such as climbing, where a secure connection is vital. Always consider the specific requirements of your activity when choosing a carabiner.
