The white nylon wheel "tyre" has split and come off on 4 other fitting like this one, 2 pairs on 2 doors and I'm trying to repair or replace them. I took this one off to see if I could unscrew the wheels off & just replace them, but they are riveted on so I will need the whole mechanism. There is no sign of any identification number or name, they would have been fitted when the house was built in 1989. Could you tell me if you anything suitable I could replace them with?
Kind regards,
Clive
