Grade 316 stainless steel is superior to standard 304 variants, offering enhanced resistance to chloride attack and extended service life in marine conditions where standard materials would degrade.

This shackle is ideal for sailors, marine engineers, and tactical equipment builders who require certified, corrosion-resistant fastening hardware. The compact 1-inch footprint makes it suitable for space-constrained applications while maintaining full load-bearing capability. Installation is straightforward—simply position the dee between load-bearing components and secure with the removable pin. The standardized 4.0mm pin size ensures compatibility with existing rigging systems and hardware chains, making it an excellent replacement or upgrade component for any Grade 316 stainless steel marine assembly.
