Do you have replacements for 2810

Hello! "2810" actually isn't a part number, it's just a code that tells us how strong the spring is. A balance's Series is based on the style and size of the nylon caps on either end. In your case, I think you may have our S395-29, but you will need to carefully go over our pictures, measurements, and information to confirm.
