Traco Window Double Hung

Hello, thank you for posting,

Please start by reviewing the 15-087 coil housing pivot that is compatible with the Series 180 coil springs. Also see the 15-086 for the tandem coil housing. For the pivot bar, please review the style of the 26-040. Compare all dimensions to confirm a good fit! 

Your coil springs should have a number stamped on the metal that indicates the weighted option needed. If there are no markings, please provide the weight of the window sash for further assistance. Let me know if you have any questions!
