A gate latch is a mechanical device used to secure a gate in a closed position. It typically consists of a metal or plastic hook that engages with a catch or plate, preventing the gate from swinging open. Gate latches come in various designs, including slide latches, spring-loaded latches, and gravity latches, allowing for different levels of security and ease of use. These latches are commonly found in residential and commercial settings, providing safety for pets and children while also enhancing privacy. They can be installed on wooden, metal, or vinyl gates, making them versatile for various applications. Proper installation and maintenance of a gate latch ensure its effectiveness and longevity.
