Thanks for posting. This looks like one of our Series 377 Channel Balances. Could you confirm that the metal channel (but not including the nylon attachments) is 24" in length? If so, see our S377-24 Channel Balance. The stamp option 2320 is for a window sash weight range of 9 through 15 lbs. Let us know if you have any questions. |
