Thanks for posting! It sounds like you may have something like our Series 600 spiral balance. With your length, it would be S600-33. However, I don't believe we have any tips that would support your sash weight. We may have to custom make a balance.
To begin, please take a look at this Custom Spiral Balance Order Form that I have started for you and fill out the rest of the information. One of our representatives will be in contact with you shortly thereafter. |
