As far as I can tell there is a gap both in front of and behind the metal frame. So if I poke something into it, it falls out the other side. Maybe I can manage to bed some wire around the back so it doesn’t. Worth trying.

Hi, On one of our uPVC windows, the handle has been pulled out by years of kids opening and closing the window and the handle being loose. Unfortunately it’s not just a matter of tightening the bolts, because the bolt holes in the metal bracket inside the window are stripped. The screws won’t...

That’s good advice. I have plenty of polarity reversing adapter leads . :)
