27" & 29" Replacement Balance Inquiry

Question

Hello,
I need to get one 27 inch and three 29 inch balances. But I want to be 100% sure of the one I am supposed to order. Can you please tell the exact model I should order? Note - there are no markings / stamps on these current ones. I am guessing the 19-26 lbs rating will work.

Thank you!!

I agree, our S350-27 and S350-29 look like the best matches. However, you should check the stamps on your old balances to confirm the best option. If you have no stamps, or if you aren't sure what they mean, you should weigh your sash on a scale to confirm the exact weight. We do not recommend estimating your sash weight in this case.
