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, close the gate and the pin snaps closed, finally, lock the pin for extra safety. 

The Mantus Mooring Snap Shackle features a locking pin to ensure the gate stays locked once secured. We believe these mooring shackles are 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

When you’re out on the water, you’ll be glad to have a reliable mooring shackle to secure your boat. Check out our sizing guides below to make the right choice for your vessel.
