Curtain kerfuffle

[Nanabana]

Hello all

a mundane question, so apologies in advance, but....
my curtains sit on old style plastic curtain tracks, with gliders that wrap around the track, do you know the ones? Well my issue is that the gliders are too large for the track, and they keep falling off. The easiest solution would be if I could get hold of these gliders in a smaller size - do you know if they come in different sizes? I've looked online, and it doesn't look like they do.. I really dont want to change the track as that will mean i need to get a drill out!

Thanks

Amazon have all different types of gliders, they appear to be differnt shapes and sizes. Are any of these any good?

By the looks of things rather than being sold in sizes they are sold to match a particular brand of track. Do you know what yours is?

thanks oreocrumbs - i haven't the foggiest where it's from as I inherited the track. I've just had a look on amazon, lots available but without the sizes i just wouldn't know which will fit. I think I'll have to measure the track's height and check in store with my ruler!

actually just checked on Amazon a little more and have found that the Harrison brand seems to give a guide on sizes in the product description, will see if any of these fit - thanks!

btw - LOVE that I can post questions on here which i fret about, and if asked to family or friends, they would look at me like i'm mad

I'm a bit mad. I have found my spiritual home here
