I searched for these years ago and could never find much in the way of an answer.
My work around and more effective solution was to install two small stainless steel eye hooks above and below the cabinet door on the side where it magnet latches and use two small bungee cords (I tied knots in the cord to shorten it so that they provided sufficient tension) to secure the door. When at destination, the cords removed the eye hooks were hidden by the edge of the cabinet door.
