A door latch is a mechanism used to fasten a door, keeping it closed. It generally consists of a spring-loaded bolt that engages with a strike plate on the doorframe. Consider it the unsung hero of door security, providing basic closure. Unlike a deadbolt, a door latch typically doesn't offer high-level security, but it prevents the door from swinging open unintentionally. They're found in nearly every home, providing privacy and a sense of security. A door latch emphasizes the everyday mechanics of simple security.
