Thank you for your patience during this busy season. We can supply this balance, but only as a custom order.
For full transparency, your exact model has been discontinued by the manufacturer and is no longer made. We sell a more modern alternative that works in all the same applications. The downside is that the spring calibration is a little different.
Because of that difference, I need you to tell me the weight of the sash, down to the ounce. That will allow us to recalibrate the spring to ensure it works on your window without issue.
Thank you for you reply. I do not have a scale that measures to the ounce. Please let me know if this information provides the needed recalibration data. If not, I will look for a scale with the needed precision. Thank you, Fred
I'm afraid that it does not. The entire reason we need the weight of the sash is because these older stamps are out-of-date and no longer conform with how the manufacturer calibrates their springs.
I'm afraid an exact weight is the only way we can move forward at this stage.
