Therma-Tru provides a tutorial on how to install the gear, top extension, and strike plate for grip style multi-point locking systems. Before installing a multi-point locking system, ensure that there is a channel with a mortise pocket routed in the door. When installing the gear mechanism in the door, make sure the gears align with the face machining in the door. The top extension should be connected to the hook end of the gear mechanism. When installing the strike plate, follow the instructions provided. Feel free to contact Therma-Tru with questions or concerns about maintaining a door unit.
