Slug Bail SS With Rocker 7/16" is a slug used to secure mains or mizzens to their spars making raising and lowering sails easier. This sail slug features a nylon barrel with a rocker that helps prevent the slug from tilting in the slot and a stainless steel bail. Sail slugs are typically secured ahead of the boltrope and inserted in the mast slot instead of the rope. Secure this nylon slug to a sail with webbing, webbing and grommet, shackle and grommet, or just a shackle. Sail slugs also keep the sail stacked in the slot when a sail track stop is used.
