My windows has 3 of these per window, positioned top middle and bottom on the inside of the window frame. These catch the lock on the window to secure the closed position.
However on some windows, I've noticed I'm missing some of these as seems like the screws have broken in the hole it once held these in.
I'm planning to replace them by carefully drilling a new holes to secure these things in, slightly above/below the old holes.
I'm in the UK and looking to find where I can get replacements? Can you advise what my best approach is?
