Broken Window Pulley for Vinyl Double Pane

Question

I've attached photos of a broken window pulley that needs to be replaced. The pulley broke in two pieces and was attached to a spring that is found on under an aluminum channel on the side of the window. The pulley appears to be gray nylon with a white nylon double roller inside.

This is from an original white vinyl double pane window that was installed when the house was built new in 1999. I do not know what brand the window are as there are no markings or stamps that I can find.

I need to order two of these pulleys. We are putting the house up for sale and need to make repair as quickly as possible.

Thanks, Mark

Hey, Mark, thanks for posting. Unfortunately, these pulleys cannot be replaced. You will have to replace the entire channel balance.

I'd be happy to help you find which balance you need, but I'll need more information. If at all possible, could I see some pictures of an undamaged balance, perhaps the other one in that same window? I'd like to see pictures of either end of the metal channel, as well as the hook found at the end of the string. I will also need to know the channel length and any numbers that are printed on it. Let me know!
