spiral balance
Hi there!
Thanks for reaching out to us. Can you upload photos of your balance? We'd like to see the inner extended spiral tip. Can you also confirm the diameter of the outer tube and tell us if this is a tilt or non-tilt window?
You said you didn't have a scale but the window's total weight is 51 pounds. Can you clarify that for me?
I don't want to replace the windows as was a lot of work to order, ship, and install. And yes 51 lbs because that is what the website said was the weight of the entire window.
Thank you for confirming that for me. Since the diameter is 3/8", we recommend the Series 900. However, the maximum weight this balance can hold is 34 pounds. We can't supply the S900 to support such a heavy weight. The entire window weight may be different than just the window sash, which is the glass panel that moves up and down. Can you remove that, weight it, and tell us what you get?
For your S900-17 balance, I would go with the yellow tip option.
Thank you for your order! Good luck with the repair, we'll be here if you need anything else.
