Latches are mechanical devices used to secure doors, cabinets, or compartments by preventing them from opening unintentionally. They consist of a movable metal bar or hook that engages with a fixed catch or strike plate. Latch locks enhance security by incorporating a locking mechanism, typically operated with a key, combination, or electronic means. Common in residential, commercial, and industrial applications, latches and latch locks provide a simple yet effective solution for controlling access and ensuring privacy. These versatile components play a crucial role in various systems, from household doors to complex machinery, contributing to safety and functionality.
