I am attempting to replace some constant force balances.
I believe they are Series 145 Balance Springs based off the design of the tongue and the type of carrier.
I need multiple sizes of coils
x10 Units stamped #3
x6 Units stamped #4
x8 Units stamped #5
x4 Units stamped #6

Hey there,

Thanks for reaching out! It does appear that you have the Series 145 Coil Springs. I've included the links for each of the requested coils below. You'll need to add each spring to your online cart individually, entering the quantity you need for each.

The carrier your balances are installed in appears to be the 15-102 Double Side Load Carrier. Take a look over the dimensions to confirm that this is the right fit for your window.
