A C shackle, also known as a bow shackle or anchor shackle, is a type of hardware used in rigging and lifting applications to create secure connections with chains, ropes, or cables. It is named after its C-shaped design, which resembles the letter "C" with a curved body.

The C shackle is typically made from strong and durable materials, such as steel or stainless steel, to withstand heavy loads and harsh environments. It comes in various sizes and load capacities to accommodate different lifting and rigging needs.

The C shackle features a threaded bolt or pin that secures the two ends of the shackle together. The pin is inserted through the open end of the C, creating a closed loop to hold the load in place. The bolt or pin may have a threaded nut or a cotter pin to prevent accidental loosening.

C shackles are commonly used in various industries, including construction, maritime, manufacturing, and transportation. They are ideal for applications where the shackle needs to be easily attached and detached from the load, as the pin can be quickly unscrewed for fast connections. Like any rigging hardware, proper inspection, maintenance, and adherence to safety guidelines are essential to ensure the C shackles' continued reliability and safety.
