A snap hook with eye lock is a specialized type of rigging hook commonly used in various applications where quick and secure connections are required. It features a spring-loaded gate or latch mechanism that allows for easy and rapid attachment to a wide range of objects, such as chains, ropes, or D-rings. The eye lock refers to the presence of a closed loop or "eye" at the end of the hook, providing an additional point of connection for the load.

The snap hook's design ensures that the gate automatically closes and locks once the load is attached, preventing accidental disengagement during lifting or rigging operations. This feature enhances safety and efficiency in tasks where frequent connections and disconnections are necessary. Snap hooks with eye locks are commonly utilized in industries like construction, marine, and outdoor recreation, where their quick-connect functionality proves valuable.

It is important to use snap hooks with eye locks that are appropriately rated for the intended load and application. Regular inspection, maintenance, and compliance with safety guidelines are crucial to ensure reliable performance and prevent accidents in various lifting and rigging scenarios.
