After surveying 3-point door lock options available in half a dozen hardware stores in Bali we decided to build our own system.
Arie designed and assembled this module which is the heart of the system. It distribute the motion of the lever to 3 points which are linked to the rods that lock the door at the top, bottom and on the side.
Those rods will lock the top and the bottom of the door.
Serendipitously i noticed a similar system used on the doors inside the US moon base of the Apple TV series For All Mankind which I watched today.
