Hello there. This looks like a Simonton coil balance system that is no longer made. We have found our 15-259 Pivot Shoe, along with Series 159 Coil Balances, can work as a substitute. We have a video that explains the conversion process. See below. To know what spring weights to select for the Series 159 springs, please give me the exact weight of the window sash that these balances support, and I can calculate it for you.
