Window balance coil and housing

A quick learner from Charlotte says:
I am looking for a replacement for this window balance but do not see it on your website. The product has a number 8 stamped on the coil. I need this product for the left and right side of the window. Can you please let me know if you have this product or a product that I can used in place of this.
Thanks, Sam

Thank you for posting. The shoe looks a lot like our 15-180. Carefully compare it to your own hardware and see if you agree. If so, you may also want to look at our 15-186 coil bracket and 15-182 coil spring bushing. If you also need the springs themselves, look at our Series 190 and see if this matches.
