Abstract
A multipoint lock for securing a door panel is described. The multipoint lock includes a first latch, a second latch, a first hub rotatable with at least one of a thumb-turn knob or a key, and a second hub rotatable with a handle lever. Upward rotation of the handle lever causes both rotation of the first hub and rotation of the second hub in the same rotational direction.
