Made with 7075 Aviation aluminum. Includes paracord and key ring. 500 pounds working load limit with applied in-line pull. This carabiner is not to be used for climbing or supporting humans or animals. When paracord is combined with a carabiner with a spring-loaded gate it creates a powerful and adaptable tool that can be used in a variety of situations. You can use the paracord in a variety of ways such as for tying down gear or setting up a temporary shelter. Unravel it and use it a makeshift rope or for simple emergency repairs such as replacing a broken shoelace. This carabiner with paracord is lightweight and compact making it easy to carry around.
