A gravity latch is a type of latch mechanism that uses the force of gravity to secure a door or gate. It typically consists of a bar or lever that falls into a slot or catch when the door is closed, holding it in place. Gravity latches are often used in outdoor applications such as garden gates, where a simple and effective latching mechanism is needed.
