Swivel Snap Shackle with Clevis Pin 22mm SS

Swivel Snap Shackle with Clevis Pin, 22mm (S2478-3) is built for demanding marine and rigging tasks where reliability matters. Crafted from marine-grade stainless steel 316, this 22 mm swivel snap shackle pairs robust strength with smooth movement to prevent line twist and kinks during operation. The jaw is designed for secure closure, yet deliberately engineered to unfasten under load when you need a rapid release in critical moments.

• Material and build: 316 stainless steel for outstanding corrosion resistance in saltwater environments, making it a trusted choice for yachts, dinghies, and industrial rigging alike.
• Spring-activated locking: A reliable, hand-operated lock closes the hinged jaw, delivering a secure connection that can still be released quickly when required.
• Swivel design: The swivel head minimizes line twist and allows free rotation under load, improving performance in dynamic marine rigging and lifting applications.
• Removable shackle pin: Facilitates easy installation, maintenance, and pin replacement without specialized tools.
• Nominal size and geometry: A 22 mm size with dimensions referenced as A – 22 mm, B – 16 mm, C – 22 mm, D – 128 mm (see diagram for full detail).
• Performance specifications: Breaking load of 3500 kg, with a standard safety factor guide of approximately 25% of the breaking load. It is the user’s responsibility to determine the appropriate safety factor for their specific application.
• Identification: Product Code S2478-3. Last updated J - 26.07.22.

What makes this swivel snap shackle unique

Unlike standard fixed-shackle hardware, this model’s swiveling head prevents torsion in lines and gear, which translates to smoother operation under sail or load. The spring-activated lock provides a decisive, one-handed closure that remains secure under tension, while the ability to unfasten under load offers a practical advantage in situations that require rapid disconnection without removing the entire assembly.

Ideal uses and scenarios

• Mariners seeking dependable rigging for halyards, sheets, and mooring lines where twist-free performance is critical.
• Boat builders and maintenance crews needing a robust, easy-to-service shackle that can be quickly replaced or re-pinned.
• Industrial rigging and lifting setups where a reliable quick-release connection is beneficial and corrosion resistance matters.

Practical tips for best results

• Inspect the locking mechanism and pin for wear or corrosion before each voyage or lift.
• Keep the pin clean and free of debris; lubricate as part of routine maintenance to ensure effortless operation.
• Verify the chosen safety factor aligns with your load expectations and environmental conditions rather than relying on a generic guideline.
