A ball catch uses a spring loaded ball mounted on a door to catch with an interfacing hemispherical indentation on the door frame. A ball catch must be fixed if it becomes too loose to hold the door closed or too tight so that it is difficult to open. A ball catch means the ball catch spring has become too loose or tight because of old age and constant use, which you can fix with a few adjustments.
