Coil balance

Thanks for posting. Is this by chance from a Simonton window? If so, the closest match in terms of design is our 15-192 Certainteed Pivot Shoe, which uses Series 170 and Series 171 Coil Balances. However, we've found the 15-192 does not fit Simonton windows easily due to the alignment nubs on its surface. The shoe may fit if these nubs are rubbed down, but I cannot guarantee it. 

An alternative solution would be to instead use our 15-259 Pivot Shoe, along with Series 159 Coil Springs. The video below explains this conversation process. Check it out and see what you think.
