🔗 How to Choose the Right Shackle for Your Project
Shackles are essential components in rigging, lifting, and towing operations. Choosing the right shackle ensures safety, efficiency, and compliance in your project. This guide walks you through types, materials, sizing, certifications, and usage tips.
🧱 What is a Shackle?
A shackle is a U-shaped metal connector secured with a pin or bolt across the opening. It forms a removable link in systems using wire rope, chain, slings, or other hardware. Shackles connect loads to lifting devices or anchor points.

🧪 Material Selection
Choose based on your working environment:
- Carbon Steel – For general purpose
- Galvanized Steel – Corrosion-resistant rigging for marine or outdoor use
- Stainless Steel (304/316) – For marine hardware or chemical exposure
- Alloy Steel – High-strength for heavy-duty or offshore use
📏 Sizing & Load Ratings
- Focus on pin diameter (not just body size)
- Always check the WLL (Working Load Limit) and Breaking Load
- Use proper sling angle and safety factors
- Match shackles with slings and lifting hardware
Example: A 3/4” bow shackle (4.75T WLL) is standard in construction lifting.
✅ Certification & Standards
Our shackles comply with international lifting standards:
- CE Certification
- ASME B30.26 – Common in US & Middle East markets
- EN 13889 – European forged shackle standard
- All are proof-tested and serialized for traceability
🧰 Best Practices for Shackle Use
- Always inspect shackles before use
- Avoid side-loading unless shackle is rated
- Use correct lifting clamps or slings for load distribution
- Don’t use damaged or modified pins
- Never exceed the rated WLL
