Window balances

Thanks for posting! We can definitely help. The balance in your second photo looks similar to our Series 385, though this is mostly an educated guess. Keep in mind that I'm basing this on the style of your nylon attachments. The Series 385 comes with a 19-005 top and 15-004 bottom, so as long as those match you should be okay.

I'm also not sure if the balance in your second photo has the same nylon attachments as all the other balances you're looking for. The stamps aren't part numbers or anything, they just indicate the spring strength calibration. You will need to compare the nylon attachments on each balance in order to confirm if the Series 385 is what you're looking for.
