Hello Andy, thank you for contacting us.
Can you give us the length of the metal channel only? Also, please give us any markings you find on the balance. |

Hi Andy,
Channel balances are only available on the full inch; I'm not sure if 33" or 32" would be better for a replacement. The 32 3 stamp translates to 3230 stamp option, found on the 33" length balance. If you prefer to try the 32" length, choose stamp option 3130. 33" Series 380 with stamp 3230 will carry a window sash weight range of 18 through 23 lbs. 32" Series 380 with stamp 3130 will carry a window sash weigth range of 16 through 23 lbs. This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |
