...Please for the love of god, before I rip the ******* door off it's hinges and start jumping up and down on it. My office door keeps blowing open in the wind, its done it about 10 times today already and I am fed up of having to get up and close it. :/ It's a regular thing on a windy day. What's the device called that's secured at the top of the door frame, bends around and has normally a wheel on it that sits on the top of the door. Its made if bendy metal. These are quite an old device and sometimes have a bell on it. Thanks.
