ABSTRACT:
A deadbolt latch body externally mounted to an interior door encasement by an unconventional method. The latch assembly, including a slotted receiver member fastened to a hinged door adjacent the latch, includes a crank-shaped shot bolt carried by the latch body for engagement with the slotted receiver. The latch bolt has al least two biased indented positions. The latch assembly may include a more secure dead bolt striker plate for existing internal dead bolts that provides even greater security when the striker plate is extended from between the door and the casement and secured between the security door latch body and the door casing.A unique mounting is provided for the latch body by providing a threaded mounting stud extending from the interior located latch body through the door encasement and retained exteriorly by a recessed threaded collar. A unique key is provided for allowing the door latch to be released from the door casement in an emergency by removing the exterior threaded collar or by unscrewing the threaded stud.
