Wichard 1243W Self-Locking Bow Shackle 6mm 1/4" 316L Stainless Steel Marine Shackle

The Wichard 1243W is a 6mm (1/4") self-locking bow shackle drop-forged from grade 316L stainless steel, engineered for reliable performance in demanding marine and rigging applications. The wide bow profile accommodates multiple lines or cables simultaneously, while the patented self-locking pin system provides a critical safety advantage over standard shackles.

The self-locking mechanism uses precisely machined indentations in the shackle body that engage matching lugs on the pin head when tightened. Once locked, the pin cannot rotate loose due to vibration or incidental contact — it requires deliberate manual force to release. This makes the 1243W ideal for use in running rigging, anchor connections, and any application where accidental opening would be unacceptable.

Key Features:

• Drop-forged grade 316L stainless steel construction for superior corrosion resistance and strength
