Hi gang -
One of our windows has slipped out of alignment, the hinges grate horribly and it won't shut without serious effort. The stainless hinges are really chewed up as a result of not doing anything, so I ordered a new pair from our friends at Screwfix.
But when I think about fitting them, I quickly get confused. How do you mark the correct drilling points when the window has to be closed to do this? Do you mount first to frame and then to opener (sask?), or is it the other way round?
There must be a trick to this, and I'd be grateful for any advice. I don't want to take 'em off and then find I can't refix 'em!
TIA
