Protecting glazing bars on sash window.

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.

You can get spring-loaded screw type sash catches, eg

At ?200 a sash, that's well, err, out of the window.

So obviously impractical I already discounted it years ago.

Need to be opened.

Nope. Now (spring repainting season) is the time to do *something*.

That won't stop people rotating them anyway.

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.

But the original link said they were for Brighton sash windows not London ;

Ones touched by the ugly stick are cheaper

Friend just brought some from here.

Those are the type I want to try to prevent from smashing up my glazing bars.

Replace the Fitch catch with a Brighton Catch

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 attached.

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 up?

The window frames aren't deep enough to rotate the "gun barrel" a whole

knock in a nail to act as an end stop.

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

Then the window would only half-open.

They are (in my experience) sprung so the screw part pops upright when released.

OK, I might get one to experiment with.
