bow shackle
A heavy-duty metal fastener in the shape of a U, the bow shackle is designed to join two or more pieces of hardware. Its main function is that of a strong, reliable connection point for lifting or rigging purposes. Technological features of this shackle include a wide mouth which allows easy fitting over large obstructions. And its high tensile strength ensures that it can withstand formidable forces. The bow form of the shackle provides extra strength. This reduces the chance of failure under load in use. It is often used in crane operations, maritime usage, construction and industrial equipment, or wherever the safe keeping of loads is important.
