Abstract

An enclosed and concealed lock device is disclosed which provides a high degree of security. The device is resistant to tampering and to brute force destruction. One or more latches are engageable with a strike plate in a door jamb or with a strike box, which is also enclosed. A seal trim prevents access to the latch. A slide assembly having a padlock is located within a latch enclosure. An orifice on a pivotal link attaches to the shackle of the padlock. Locking the padlock raises the padlock body into the protective latch box enclosure, and prevents movement of the slide assembly. A first limiter restricts vertical movement of the shackle, allowing the padlock to be engaged by upward movement of the padlock body.
