Spiral balance replacement for my double hung windows

Question

I am looking to replace both the spiral balance and the shoes in 4 of my double hung windows.

For the Spirals: they are 29" long and appear to be 9/16" in diameter. There is a blue tip at the bottom of the ones I want to replace.

Is that an indicator that I should order the replacements with blue tips?

For the shoes: My current shoes have the blue plastic insert for the window. Since it appears I am ordering the Series 600 Spiral, would the correct matching shoe be: 15-015.

Many thanks...you guys rock.

Thank you for the compliment. Starting to talk about the Series 600, when you go to the store page you will see a sash weight chart of the different colors to choose from based on the weight of your sash. As for your pivot shoe, if the measurements and dimensions of your pivot shoe match up with ours, then you should be ok to go.
