Striker Plate

Door Latch Striker Plate

The door latch mechanism (the point at which the door latches to the door post) consists of two parts - the striker plate on the door post, and the latch on the door. If the door rattles or requires excessive force to close and lock, the door latch striker plate is probably out of adjustment.
