A mechanical fastener designed for securing doors, gates, or panels features a pivoting component. This pivoting action allows the device to engage with a corresponding strike plate or keeper. Rotation of the latch component moves it into a locked or unlocked position, providing a simple and reliable means of closure. An example would be found on many types of garden gates, where a metal arm swings to engage a post and secure the gate closed.
This type of fastener is valued for its ease of use, durability, and adaptability to various applications. Historically, similar mechanisms have been employed for centuries in securing everything from simple chests to complex door systems. The benefits include straightforward operation, resistance to forced entry (depending on design), and a generally low manufacturing cost, contributing to its widespread adoption.
