Self Locking D Shackle (5mm - 10mm)

A self-locking D shackle is a robust piece of marine hardware designed for secure and reliable connections in boating and maritime applications. Constructed from durable materials such as stainless steel, these shackles feature a mechanism that automatically locks the pin in place once it is engaged, preventing accidental opening.

In boating, self-locking D shackles are commonly used for connecting rigging components such as anchor chains, mooring lines, and towing equipment. The self-locking feature provides added security by ensuring that the pin remains securely closed under load and vibration, reducing the risk of accidental disconnection.
