This is a clone of a simple drawer child lock from IKEA (PATRULL). For some stupid reason, these are no longer available in my country.
With careful placement, it can also fit regular cabinet doors.
The larger part is fixed inside the drawer/door, the small part should be fixed to the inner cabinet wall. I used 2x20mm wood screws.
Opening: the drawer will extend slightly, push the arm to unlock and open.
Closing: the lock will latch after the door is closed
