Mortice Latches
A door latch is a simple sprung latch that keeps the door shut once it is closed. They are normally operated with a door knob or lever but can also be a simple push open/close roller latch. The latch mechanism can be upright or tubular.
It can be used with a door lock for security.
(A dead lock combined with a spring latch is known as a Sash Lock.)
