Got a door which does not have the spring lock which locks the door when you close it. Leave the door closed, and it'll soon be wide open even with a little gust of wind.
Currently we're wedging a handful of paper between the door and the door frame, so that it'd stay closed when we close it. The more elegant option of course, is to use a damper which will slowly close the door once it's been opened.
But dampers are a bit expensive for such a trivial function, and then there are the installation charges too. Is there a better way to ensure the door remains closed (a simple, elegant, less expensive option. Installing a spring lock is expensive)?
