Hi all,
I thought buying new handles would fix my two stuck UVPC windows, but it only fixed one! The second is stuck locked. I can move the new handle about 45 degrees before it won't open any further and I don't want to force it. I've done some searches on this, but most of the lock featured in the results are very different to my 'U shaped' one. Knowing the name of this lock might help! Please see images for more details. Any ideas very gratefully recieved.
Cheers!
