Constant force coils

Home Owner from Grantsville WV

I have 3 the above windows. 2 of them have broken coils on the bottom. I would like to purchase 4 pair of the bottom units and 2 pair of the top ones. The first picture is the top ones and the last picture is the bottom ones.

Thank you

Charles

Hi Charles, thank you for posting,

Your balance assembly resembles the 15-087 pivot housing that uses the Series 180 coil springs. Please review the overall dimensions below to confirm a good fit! You will need to reference the number on the original pivot housing to pick the correct coil weight. If you need further assistance on this, please let me know!
