I've got several sash windows divided into multiple pane with glazing
bars. The problem is they have rotating catches, which if clumsily
positioned act as a plane and shear off the top few mm of any glazing
bar they encounter.
One solution would be a different catch, or perhaps more simply some
kind of robust sculpted cover for the glazing bar that the catch would
bounce off instead.
They are quite loose rotationally, and people knock them. In any event,
I can't educate every single window-opening person to be right 100% of
the time, and it only takes on bump every 5yrs to destroy the look of
the glazing bar.
[ps I just won a side bet that the first response would be like that]
You might want to avoid "london" prices!
or if you don't need the screw bit:
I wonder why they show the further part almost vertical, when it would
need to be fixed horizontal? And of course, when you close the window if
the screw part isn't exactly vertical it'll take off a bit of external
glazing bar on the outside of the lower window this time.
Those are the ones I have now, where the crescent bit planes off chunks
of the inside of the upper window's glazing bars if you aren't careful.
Er, merely an example.
better? You do have to make sure the spring loaded part is
mounted far enough from the glass that it doesn’t smash the
window when released :-P
The "gun barrel" part is going to end up hinging so it is pointing
upwards, then travelling downwards with the window frame to which it is
What will prevent it bumping on the exterior glazing bars of the lower
window on the way down, and taking chunks out of them on the way back
The window frames aren't deep enough to rotate the "gun barrel" a whole
180 degrees to point towards the garden.
