I am needing 2 sizes of window balance. Each window has 2. The smaller balance shown is used for a sash that weighs 11 pounds, The lager balance is for a sash that weighs 20 pounds.Sold by America's Windows, Charlestown IN, in 2007. I also need to know if you have sash stops and Balance covers.

Hello! We do not sell sash stops or covers, unfortunately, but we do sell balances. I recommend the 15-177 pivot shoe, which is designed to be compatible with the Series 152 spring. I am very confident that these parts will work for you.

Thanks Tom,
Will the S140 work. in it's place. I was wanting to replace the entire assembly. I have one window that has a single coil spring ( Window weighs 11 lbs, and the other sash weighs 20lbs and has a dual coil with 2 screws fastening the assembly.

Hi there! You won't be able to use our Series 140 as a replacement because your original hardware corresponds to our 15-177 pivot shoe and Series 152 Coil Balance. However, you can use the hardware I've associated on the side to replace your assembly. Best of luck with your repair!
