I have an existing double-hung white window with a broken piece that keeps the top half secured up when open. Looking for replacement piece.

Hello, thank you for posting,

Your balance assembly resembles a style that is no longer made. We recommend reviewing the 15-259 pivot shoe and the Series 159 coil springs as a suitable replacement option. Please review the step by step video below that details the conversion and additional parts needed. Let us know what you think and if you have any additional questions!
