Duplex Mooring Snap Shackle




The Mantus Mooring Snap Shackle is designed to easily and securely attach a boat to a mooring ball. Simply load floating mooring line or the metal ring into the snap shackle and close the gate and lock the pin. The Mooring Snap Shackle features a locking pin to ensure the gate stays locked once secured. We believe this is the the strongest and the smartest way to moor your boat.



  • Made from Duplex Stainless Steel to be stronger and more corrosion resistant.
  • Features a proprietary secondary pin locking mechanism that ensures the gate stays closed
  • Currently available in 1/2 inch and 5/8 inch version, please select size above to see product dimensions
