29 inch spiral balance




Hello,
We'd be happy to look into this for you but we would need to see the end of the spiral and confirm if the diameter of the housing tube measures 3/8" or 5/8". There should also be a colored piece of plastic at the base of the housing tube. If the colored piece is missing, you'll need to weigh your sash to determine the strength option needed for your replacements. There is a chart on the product page that explains how to choose your option based on the sash weight. Thank you!




We can't be sure of what you need without seeing the end fop the spiral that attaches to the sash bracket but the S500-29 would be a good place to start. Take a look and let us know if you have any other questions or concerns.
