Hello. I am going to replace the channel balances of 15 windows and need to make sure I order the correct ones. I think the ones I need to order are 390-28 but please confirm for me. The measurements are 28in x 1/2 in. My windows are non tilted and there are no wings on the guides.

These pics are from 1 window different from the others... it's heavier and the measurement is 22in by 1/2in. Not sure if it matters but my house was built in 1989.

Hello, thank you for posting!
It looks like you have either our S351-28, with a 15-002 bottom attachment, or S390-28, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.

Comparison of the S351 and S390 balance shoes.
Once you determine which series is needed, you will need a 28" length with a 2730 stamp option and a 22" with a 2140 stamp option. Please let me know if you have any questions!
