Each guard plate includes a support plate having a generally rectangular shape and including a cutout which allows for the protrusion of either a latchbolt plate or a strike plate. A pair of flanges extend respectively in opposite directions from opposite edges of the support plate. Preferably, the flanges are perpendicular to the support plate. One of the flanges includes an aperture for receiving a tongue and the other flange includes a tongue which extends in generally parallel relation to the support plate.
