Hello, thank you for posting, Please review the S140-15 coil balance as a replacement option. Compare the dimensions below to your original to confirm a good fit! Each balance can support 15 pounds of weight. Together, the total window sash weight should weigh 30 pounds. Let us know if you have any additional questions! Alternate image for S140-15
