Shutter track gliders

[maximax]

Hi,
The track gliders for our window shutters no more hold the screws so need replacing. I don’t know the brand and just cannot find anything similar looking on the web, so could anyone here point me towards a source for spares? Many thanks.

Obviously you'd need to check sizes to ensure they'd fit, however would you not be best just replacing the whole lot i.e. including the runners? Something like this?
