Prehooks

Prehooks is a term used in multiple domains to describe preparatory hooks or hooks used to enable rapid, secure pre-attachment before a primary action.

In rigging and lifting, a prehook is typically a secondary hook, latch, or attachment integrated with or used alongside a main hook or shackle. It is designed to receive or stage a load line, sling, or chain so that the main hook can be engaged quickly or in a controlled sequence. Prehooks help reduce setup time, minimize line snagging, and improve rigging reliability during lifting and towing operations. They come in various forms, including latch-type prehooks and quick-release variants, and must be compatible with the load rating of the system. Regular inspection, correct threading, proper alignment, and compliance with relevant standards are essential for safe use.

In software engineering, prehooks refer to functions or callbacks that execute before a principal hook or event. They allow preconditions to be checked, inputs to be sanitized, or context to be adjusted before the main handler runs. Prehooks are common in event-driven architectures and middleware pipelines, where they can modify arguments, enforce security checks, or veto operations if conditions are not met.

In manufacturing or textile hardware, the term may describe pre-attached hooks that are mounted on components to speed assembly or garment fastening. Terminology and specific designs vary by industry, and the general concept is to provide preparatory attachment.

Safety and standards emphasize rated capacities, material quality, and traceability. Users should follow manufacturer instructions and industry standards for inspection and maintenance. See also: hook, carabiner, quick-release, rigging, middleware, pre-processing.
