Abstract: Latches are used to secure the legs of a stepladder during transport or while the ladder is leaned up against a wall or other surface. Embodiments for both extruded and solid-leg ladders are disclosed. A latch according to the invention includes a first latch portion mounted to one of the legs of the stepladder, and a second latch portion hingedly affixed to the first latch portion. In an unlatched state, the second portion is folded out of the way, enabling the stepladder to be used as a stepladder, and in a latched state, the second portion folded onto the other leg of the stepladder to hold the two legs together.
