Happy new year! I have some 6500 series double hung windows (I think simonton) purchased and installed by home depot in 2010. At least one shoe on each window is broken. I removed the whole balance assembly (had to cut a bigger hole) and pulled everything out. None of the coils have any numbers or letters stamped on them. The top coil wasn't even attached to the bottom one or shoe. I can't even get the barrel for the top coil to fit anymore either.
Are you able to identify these parts for replacements? I would need 8. Thanks.

Happy new year! We appreciate you reaching out to us. If you have a Simonton brand window, my recommendation would be the 15-259 and Series 159 coil springs. Our video below will detail the process. You will also need to divide your sash weight by the total number of springs in your window to determine the appropriate coil weight.

Thanks. Sash is 26lbs so four 6.5 is needed I guess. Do you have a complete assembly for double Coil, shoe, Support bracket, drum, etc or do I need to purchase each separately? Thanks

I'm afraid we don't sell these parts as a complete set so you would need to add them to your cart separately. For a new double coil support, I recommend our 15-256.
