Window balance and coil?

Hello! Right off the bat, your pivot shoe reminds me strongly of our 15-048. I think this may be just the party ou need, but review our specs and see if you agree.

As for the spiral balance, our S600-37 looks like a good fit. The Black Tip color option holds sash weights in the 31 through 40 pound range, so that should be perfect.

Please look these parts over and let me know if you had any questions!

No, the color tips for our balances are weighted under the assumption that two balances will be carrying the load. You wouldn't divide it in half. The Black Tip will carry your sash weight perfectly.

Not necessarily, no. As long as your balance is still in good working condition I see no reason why you have to replace that.
