I've converted my garage to an office and in the summer I often leave the
door open to get a little fresh air. The garage door opens outwards and if
the wind catches it, it really can fly open. To stop it actually hitting the
wall I attached a chain at the top to limit it's movement to about 90
degrees. Last week though the wind caught it again and it flew open so fast
that when the chain stopped it I think the whole door must have twisted and
the glass broke. As it was pretty tatty anyway I've now fitted a new door
and want to prevent the same thing happening again. What I need is some sort
of dampening device to stop it opening too quickly and to limit it's
movement. I've looked at those automatic door closing mechanisms but I don't
think that's what I want.

Anyone got any suggestions?

TIA
