ABSTRACT:
A latch assembly for preventing access into a door or drawer is provided. The latch assembly includes a housing configured to mount on a door or drawer, and at least one dog is slidably mounted in the housing for movement between a locked position and an unlocked position. The latch assembly include actuators operatively connected to the dog for moving the dog to the unlocked position. A key is insertable into a key slot on a side of the housing to move the actuators. The latch assembly may be used in combination with a catch assembly configured to mount on a door or drawer frame. The catch assembly is constructed to engage at least a portion of the dog in the locked position. The catch assembly may include a spring to move the latch assembly relative to the catch assembly such that the door or drawer may open slightly while in the locked position enabling a key to be inserted into the key slot to move the dog to the unlocked position.
