An improved latch plate in combination with an anchor base plate designed to resist forceable entry when disposed within a doorjamb. The construction of said latch may be adapted to engage either a sliding bolt or dead bolt when disposed over the bolt recess of a doorjamb. The latch has a flat plate portion with a large opening to receive a bolt, the flat plate has anchor corner and lip end, with an anchor stem extending inwardly towards the doorjamb and perpendicularly from the inside of the flat plate at the anchor corner. The anchor stem is in bearing contact within the doorjamb recess of the door frame and protrudes through a longitudinal aperture located in the anchor base plate into the doorjamb frame. The anchor base has a plurality of apertures disposed on both sides of the longitudinal aperture and are so located to cooperately receive the screws from the latch plate. The location of the plurality of apertures disposed on the anchor base plate is such so as not to cause a splitting of the wood frame into which they are screwed due to their offset. Traverse to the plurality of screws of the anchor base plate are a pair of safety screws disposed into the doorjamb through apertures located in anchor stem of the latch plate. Both the anchor stem of the lock strike plate and anchor base plate are concealed from view when mounted on the doorjamb. A tab extends into the doorjamb framing from the large opening disposed on the flat portion of the latch to further increase the strength of the assembly against unauthorized or foreceable entry by means of kicking and/or pushing against the door. Thus providing the occupant of a dwelling with improved security as compared with conventional lock strike plates.
