Ronstan Standard Dee Shackle - 6.4mm (1/4") Pin

The Ronstan Standard Dee Shackle with 6.4mm (1/4") Pin is a marine-grade rigging connector engineered for reliable load bearing in demanding nautical, industrial, and tactical applications. Designed for sailors, riggers, and equipment specialists, this dee shackle serves as a critical anchor point for lines, cables, and hardware where secure attachment and easy release are essential. Its compact footprint and robust construction make it ideal for situations where space is limited but strength cannot be compromised.

Crafted from Grade 316 stainless steel for both body and pin, this shackle delivers exceptional corrosion resistance and a superior strength-to-weight ratio that outperforms standard carbon steel alternatives. The 6.4mm pin diameter provides optimal load capacity while remaining lightweight at just 0.1 lbs, making it suitable for both permanent installations and portable field use. The dee-shaped design distributes force evenly across the shackle body, reducing stress concentration and extending service life even under dynamic loading conditions typical of marine environments or tactical gear systems.

This shackle is favored by sailing crews, rescue teams, outdoor professionals, and equipment riggers who depend on dependable hardware in saltwater, freshwater, or high-vibration settings. The stainless steel construction eliminates rust and degradation concerns, ensuring long-term reliability without maintenance. Compatible with standard 1/4-inch rigging systems and hardware, the Ronstan Standard Dee Shackle (MPN RF617) integrates seamlessly into existing tackle, anchor systems, and load-bearing assemblies where corrosion resistance and durability are non-negotiable.
