Window balance replacement pulley
Best regards,
George
Thanks for writing in! The pulleys on balances, in general, cannot be repair or replaced. In instances where the cord snaps and the spring becomes damaged, the entire balance assembly needs to be replaced.
In regard to the balances, I'm sorry to say that I am not familiar with the balance assembly you have here. To determine if there is a suitable replacement we can supply you with I'll need a bit more information about the hardware.
To start, may I see a photo of an undamaged balance removed from the window? It would also help to see photos of how it installs in the space and photos of any other hardware compatible with the balance.
Please let me know if you have any questions in the meantime.
