ABSTRACT:
A device for selectively locking a door in a closed position against a door frame member having a body with a substantially planar mounting surface for engaging the face of the door and a throughbore in the body substantially parallel to the mounting surface. A mounting mechanism included for coupling the body to the door. A magnetic bolt is disposed within the throughbore for slidable movement between a retracted position and an extended position wherein a portion of the bolt extends outwardly from the body when in the extended position. A retainer is included for limiting the travel of the bolt between the retracted and extended positions. A striker is mounted to the door frame member for engaging the bolt in the extended position so as to secure the door against the door frame member in the closed position.
