We appreciate your patience as we checked on this for you. The balance with 6#27 stamped on it would use the 24-637 replacement. The other stamp code indicates that you would need the 24-R12-827 Andersen sash balance and the opposite-handed version would be 24-L-8-1227. Take a look and let us know if you need anything else. |
