The ball bungee cords are for securing tarpaulins to canopies or other fixed points. Slight movement can help extend the life of the tarpaulin and grommets. Simply loop through a grommet and support and then lock it over the ball. Depending on the project, the loop end could be hooked to an object or other bungee, or the ball end could be slipped into a hook or other fastener, or the whole thing could be used as a small single-strand loop. They prolong the life of tarps and grommets by allowing slight movement, can survive all weather conditions, and are reusable.
