Latch

A latch is a metal piece that extends into the doorjamb to secure it shut. The latch can be operated by a knob or handle located inside the door, or by a thumb-turn on the outside. A deadbolt can be used to secure a latch and stop burglars from piercing the glass of the door. It can also guard against intentional or accidental closing by pets or children.
