A multi-point lock assembly includes a pair of spaced apart latching members for locking sliding doors, windows or other similar structures. The lock assembly includes a housing rotationally supporting a pair of actuators provided with a plurality of gears arranged in meshed engagement with one another. Rotation of one actuator causes rotation of both actuators in opposite directions, that is, one clockwise and one counterclockwise. Short and long arm assemblies are respectively pivotably connected at their proximal ends to an extended portion of the actuators. The distal end of each arm assembly is guided by a pin received within a track provided in the sidewalls of the housing. The latching members are formed as threaded bolts received within the distal end of each arm assembly. As the actuators are rotated, the distal end of the long and short arm assemblies track along the track within the sidewalls. The shape of the track causes each of the bolts to be displaced vertically and longitudinally along the longitudinal axis of the housing from an unlatched position within the housing to a latched position extending outwardly therefrom. The bolts are adjustable by varying their threaded engagement within the distal ends of the arm assemblies for alignment with the opposing keeper.
