I finally got around to putting the window in my painted sliding door. Once I got the door back on, I remember now that I'd never had any joy getting this door to close nicely and sit right. I should start by saying that I believe that it may have had some filling at the bottom at some point.
Basically, if you shut it with a normal push, it doesn't latch in fully, so sticks out at the back. If you give it a firm push, it does go in, but when the handle is turned it 'pops' open - ie. like it's being held in a position by the latch that it doesn't want to be in. In one of the photos below, you can see that there is a daylight gap at the leading edge.
I've read a few 'how to adjust' threads, but can't seem to get the suggestions to work.
I've taken a load of photos in the 'firm closed' position in case any of you get a chance to cast your well trained eyes over..









Thanks,
Stu
