Coil Balance Replacement

Question

Hello, I need to replace these (pics attached) for 5 M/I Windows that are single hung. They have a "9" stamped on the coil. Three of the windows measure 62.5H x 34.5W and two measure 70.5H x 34.5W. Can you please let me know the exact part to order?

Thank you,
Jamison

Thanks for posting, Jamison. I am going to list a number of parts that should help replace your current balance. Take a look at the following part numbers for consideration: our 15-080 coil balance shoe, 15-181 double support detent clip, and 15-182 balance bushing. The S190-640 Coil spring may be a match for your current spring. We actually think the "9" stamping is actually a 6. We'd like to see the number on your spring to confirm. We recommend to only replace what is broken.

For the remainder of your windows with different sizes, you will need to check the springs for their spring weight numbers as well.
