What is the purpose of a striker plate for a door and how does it contribute to the overall functionality and security of the door?

A striker plate for a door is a metal plate attached to the door frame that the door latch or bolt engages with when the door is closed. Its purpose is to reinforce the area where the latch or bolt secures the door, making it more secure and preventing forced entry. The striker plate helps distribute the force of any attempted break-in, enhancing the overall functionality and security of the door.
