  • a lock generally comprises a deadbolt which can be moved between a locked position and an unlocked position, for example by means of a key.
  • a deadbolt which can be moved between a locked position and an unlocked position, for example by means of a key.
  • the lock may also include an inner square and an outer square.
  • the term interior is used in reference to the part of the lock located inside a space to be secured, and the term exterior is used in reference to the part of the lock located outside this space.
  • An interior handle can be mounted on the interior square, the interior handle being integral in rotation with the interior square.
