U-Type Shackle Details

A U-type shackle is a robust, U-shaped metal link fitting, usually made of high-quality carbon steel with hot-dip galvanized finish to ensure excellent corrosion resistance and long-term durability. It consists of a forged U-body, a threaded clevis pin, a hex nut, and a split cotter pin, forming a secure, vibration-resistant connection.
The hot-dip galvanized surface provides a uniform protective layer against rust, moisture, and harsh outdoor environments, making it ideal for overhead power lines and outdoor installations. The one-piece forged construction guarantees consistent tensile strength, while the removable pin allows for easy installation, disassembly, and maintenance.
Core Function
This shackle serves as a critical connection point in overhead power transmission lines, distribution systems, and structural support projects. It is widely used to connect insulators, conductors, stay wires, and other hardware fittings to poles, towers, or anchor points. Designed to transfer tensile loads safely and reliably, the U-shaped body accommodates the attachment of cables or connectors, while the locking nut and cotter pin prevent accidental disengagement, ensuring stable performance even under dynamic loads and vibration.
