Hi there!
I thought I would have to replace my whole window, but then I found your website. The old vinyl sash window has no brand name that I can find.
The sash weighs about 17 lbs. I don't have the hook part you ask for in the video. I think i threw it out with the broken cord. I hope I have provided enough information for an identification.
Thanks
Paul

Hello, It looks like you have either our S351-24, with a 15-002 bottom attachment, or S390-24, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. If take out clips are needed, please see our 16-002. 
Comparison of the S351 and S390 balance shoes.
The spring strength you had was a 2340, but since your window sash weighs 17 pounds I would recommend using stamp option 2330 instead so the window sash functions properly. Please let me know if you have any questions. |
