I could not find any markings on the frame, glass, or parts. It is most likely a builder grade window installed in the home. I need to two replacements.

Hello

Take a look at our S775 channel balance. If there is no stamp on your metal channel, you'll need to weight the window sash and choose a spring strength option under the product description on our website. Thank you!

Great. Then you'll choose one of the 2200 strength options with the width of your hook attachment.
