Abstract

A multipoint locking system includes a body having an upper aperture and a lower aperture therein. An upper latch pawl is disposed in the upper aperture and is pivotable about a first vertical axis between a first retracted position and a first extended position. A lower latch pawl is disposed in the lower aperture and is pivotable about a second vertical axis between a second retracted position and a second extended position. At least one actuator is configured to move the upper and lower latch pawls between their retracted and extended positions. The body can be an astragal, a vertical frame member, or the like.
