Our D shackles (also widely known as dee shackles or chain shackles) are specifically designed for straight-line tension and high-load lifting operations. As a specialized metal fabrication factory, we ensure each shackle is forged to withstand the toughest industrial environments.
Superior Durability: Available in 304/316 Stainless Steel for marine anti-corrosion and Galvanized Carbon Steel for industrial strength.
Precision Engineering: Screw pin design allows for easy attachment and secure locking.
Certified Safety: Every batch undergoes rigorous load testing to ensure a high safety factor (e.g., 4:1 or 6:1).
Versatile Applications: Ideal for maritime rigging, construction crane systems, and vehicle towing.
