A gate latch is a simple mechanical device used to secure a gate in a closed position. It typically consists of a metal or plastic hook that fits into a catch or loop, preventing the gate from swinging open. Gate latches can be operated manually, allowing users to easily open and close the gate as needed. There are various types of gate latches, including slide latches, spring latches, and gravity latches. Each type has its own mechanism for securing the gate, but all serve the same primary purpose: to provide safety and privacy by keeping the gate closed when not in use.
