Hooks are the anchor places for hammocks. All of our weight will be hold by those little steels. For the reason, we should choose the hooks with finest material qualities. There are at least two types of hooks: tree hook and S hook. We need to drill a hole as an inserting place of a tree hook. The S hooks are usually accompanied with chains as its extensions to the hammock. We need not drill a hole with this hook, so it’s more eco-friendly than the tree hook. Moreover, S hook is usually used as a connection between the hammock and ropes which wrapped to the trees.
