Using these soft shackle carabiners is easy. For hammock suspension, simply attach the shackle to the appropriate points on your hammock and the support structure. They can also be used in other scenarios where you'd typically use a carabiner, like in some DIY projects or for securing light - weight items. When it comes to maintenance, keep them clean and dry. Avoid exposing them to sharp objects that could cut the amsteel material. If they get dirty, you can gently wash them with mild soap and water, then let them air - dry. Also, always double - check the weight limit of 125kg to ensure safe use. Remember, the XL size is shown in the first photo and the regular size in the others, but they work the same way, so pick the size that suits your needs best.
