Anderson Narrowline Balancers - replacement parts

Thanks for reaching out. If your old balance is stamped with "4 25," then you may very well need our 24-431 Andersen sash balance. Just note that ours is a more modern version compared to your original model, so some adaptation may be necessary to get the newer part to fit in your header.

Great! Thank you very much, we really appreciate the business. I'm here to help if you had any other questions in the future.
