Hi there! This looks like our 3/8" diameter S900-34 spiral balance. Since your sash weighs 19.2 pounds, you could go with either the White or Green tip strength option or whichever is original to your balance. Let me know if this makes sense or if you had any questions. |

Your sash weight falls within the Green and White option so you could really go with either. The decision is ultimately yours! |
