Sash Balances for Bonneville Windows

A home owner from Vermont says:
I want to make sure that your 33" Series 751 Channel Balance is the correct product for our windows. We have Bonneville double hung tilt and wash sashes from 2004. Each sash weighs about 28 lbs, so I am thinking of the 32 HD (as indicated also on the stamp on the original balance.

It looks like it will work, but can you verify that?

Many thanks.

Yes, I agree. Our S751-33 appears to be the best match. I would also recommend the 32HD option.

Thank you. These work perfectly and they are higher quality than the originals. The springs are more flexible so the sashes go up and down more easily than ever and they seem like they will last longer. We are very satisfied and will be purchasing more soon to replace the originals, more of which have now broken.
