ABSTRACT:
Several different designs of striker plate assemblies, for providing a stronger construction so as to resist a forced entry by applying pressure against a door; a first design including the striker plate secured to a metal angle fastened to a door frame beam in two different planes; a second design using a metal block instead of the metal angle of the first design; a third design having the striker plate itself made in an angle shape, so as to be fastened by screws in two different planes; a fourth design being a modification of the second design, in which the metal block includes a flange extending behind a door frame; and a fifth design of the invention including a metal block, which additionally is secured to the door frame in a third plane, so as to form a three-dimensional securement against a shearing force from any direction.
