Description
Versatile Butterfly Shackle – High WLL for Heavy Lifting & Rigging
Engineered for Extreme Loads, Built for Global Safety Standards

When heavy lifting meets unpredictable site conditions, you need more than a standard shackle. The Versatile Butterfly Shackle is a next-generation heavy-duty rigging component, designed for high Working Load Limits (WLL) across offshore, construction, and industrial lifting applications. Unlike traditional bow or D-shackles, the butterfly design offers superior angular stability, reduced stress concentration, and faster deployment—making it the preferred choice for safety-conscious engineers in New Zealand, the USA, Germany, France, and the UK.

Key Product Features
  • Butterfly Symmetrical Body - Eliminates directional assembly errors; fits multi-leg sling configurations perfectly
  • Heat-Treated Alloy Steel (Grade 8 / Grade 10 option) - Exceeds ASTM A952 and EN 13889 standards
  • WLL Range - 2T to 55T (custom up to 150T available for offshore projects)
  • Fatigue-Rated Design - Tested to 20,000 cycles at 1.5× WLL
  • Corrosion Protection - Hot-dip galvanized + zinc flake coating for NZ coastal and European offshore environments
  • Magnetic Particle Inspection (MPI) - 100% tested, with traceable serial numbers
What Makes It Different?
Most shackles focus only on breaking load. Our butterfly shackle solves three real job-site frustrations:
  • No more seized pins - The inverted pin retention system uses a stainless steel coil pin + safety bolt, not friction threads. Unlock with one tool even after months in salt spray
  • Visual WLL indicator - Laser-etched WLL on both sides plus a color-coded heat shrink band (red=5.3T, blue=8.5T, etc.) for quick pre-use inspection
  • Self-aligning lug seat - Reduces edge-loading by 18%, proven in third-party tests (DNV certified)

These three features alone reduce inspection time and human error—key for NZ's Worksafe and EU's DGUV compliance.
