What type of hook is described as having a wide, deep throat that fits the handles of molds or casting?

The type of hook that features a wide, deep throat designed to accommodate the handles of molds or casting is indeed the foundry hook. Foundry hooks are specifically engineered for use in environments such as foundries or factories where metal castings are handled. The design of the foundry hook allows for a secure fit over the handles, enabling safer lifting and transport of heavy objects like molds. This unique shape ensures that the hook can grasp the mold firmly without slipping, which is crucial for maintaining safety during rigging operations.

In contrast, choker hooks are designed for use with slings to create a choke hold around the load, offering different functionality than that needed for molds. Eye hooks have a loop at the top for attaching a rigging line but do not have the specialized design for handling molds. Swivel hooks, while versatile and allowing for rotation, are not specifically tailored for the unique demands of foundry applications.
