A ship shackle is a U-shaped metal fitting whose open end is closed by a bolt, which may be threaded. Ship shackles are large and heavy. NauticExpo offers coupling shackles, anchor chain shackles, Kenter shackles, etc.
Different types of shackles have different uses. Unthreaded types are found in fastening, towing, suspension and hoisting applications. Kenter shackles are used primarily for joining lengths of anchor chain. Threaded shackles can be used in the same situations as conventional models.
Ship shackles generally are of steel or various alloys. Some shackles have forged marks to indicate sling angles.
Choice will depend on shackle size and load capacity.
