Simonton window balance

A handy person from NC says:
I am looking to replace the coil balance on my Simonton window. After removing the parts it has 4089 typed onto the balance where it screws to the sliding component. I need two of these.

Tom from SWISCO responded:
Thank you for contacting us. Based on your information and photos, I believe you may be able to go with our S170-408 coil spring balance.

If the remainder of your original parts are still in tact, you may be able to reuse them with the coil spring.
