Measurements and colors to identify spiral balances

Question

Hello,

I need to replace a few spiral balances in my windows, but I need to make sure I order the correct replacement parts. Could you please help me identify the part numbers of the spiral balances based on the below measurements and attached pictures?

Here are the colors and measurements of the spiral balances I need to replace:

- 5/8" diameter, 25" length, blue
- 5/8" diameter, 27" length, blue
- 5/8" diameter, 27" length, red
- 5/8" diameter, 17" length, yellow

Thank you.

Hello there. If you're certain all the outer tube diameters are 5/8", then these are Series 600 Spiral Balances. Sometimes with the flimsier old plastic tubes though, the diameter can be tricky to measure, so please double-check to be certain. For instance, there is no yellow tip for the S600-17; but there is for the S900-17. So confirm all these diameters. Get back to me with those diameters and we can go from there.
