Automatic door catch - Hafele

This automatic door lock locks double doors without an additional strike bar or furniture latch. The door lock is mounted inside the cupboard. The hook or wedge part is mounted on the right or left inside of the door. The door with the hook part must be closed first. The wedge part then locks into place with the automatic door lock when the second door is closed. The door with the wedge part mounted must now be fitted with a lock.
