I have two windows in need of repair. On one, the bottom window doesn't stay up and on another, the top window doesn't stay up. They both have the same #s on the balance as shown on the photo I've attached. I can't seem to find what I'm looking for online or at least don't know how to look for it. The blue label in the first photo is on top of the window but it doesn't seem to list a manufacturer. I hope you can help.
Thank you,
Maria
It's going to be tough. Looks like whoever labeled this window didn't give us much to work with. You're right about the sticker... it doesn't give the manufacturer's name.
I do recognize the channels themselves. However, the photos only show part of the tilt balance, but not the attachments, so we can't pick out the Series for you. Remove at least one of each balance, take a look at the whole thing, and compare them to our Series 770 and Series 775 balances. It could be one of those two.
It looks like your pivot shoe is our 15-179, which is compatible with our Series 770 tilt balance. This means that you'll need our S770-19 with a spring weight option of 19C and our S770-21 with a spring weight option of 21B.
