I have a UPVC french door which wont lock unless you lean on the handle. Lock works fine when the door is open. I tried opening the slave door and then tried the lock, so it was just the bolts into the frame top and bottom - the lock was difficult again. The bolts go through the metal bits but hit the plastic frame.
Is there a way of adjusting the length of movement of the top and bottom bolts or do I just drill a hole in the frame?
