Allslip Round Slug is a low friction nylon plastic alloy slug used to make lowering sails easier. This sail slug has excellent strength and is long in length to reduce the possibility of jamming. Shoulder works well for compression loads. Sail slugs are typically secured ahead of the boltrope and inserted in the mast slot instead of the rope. Secure the 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. Ideal for full batten applications.
