Need new block and tackle for several windows
Thanks for reaching out! It looks like you have an older style, discontinued balance. However, there is a chance that we can provide you with a suitable replacement.
I'll just need to see a photo of the balance removed from the window as well as any other attachments and accessories that are installed in the window. These could include a pivot shoe as well as pivot bar.
Once we are able to review these photos, I'll be able to confirm if we can get you set up with a replacement.
I also noticed that you have tilt latches pictured here. If you are considering replacing those as well, I recommend starting with reviewing our 26-243 and 26-244.
All of my windows are the same and apparently they had replaced one window with these block and tackle so these were apparently work I will send you the pictures
The weight of the window is 18.5 pounds.
Thanks for the photo. It looks like you'll need the Series 795 Channel Balance. To confirm which one you need, you'll need to confirm the length of the metal channel.
Once you've confirmed the length, you'll be able to select the balance you need. Then you'll need to use the chart below the product description to confirm the stamp needed for your 18.5lb sash, based on the weight ranges shown. Let me know if you have any questions.
