Thanks for posting! Based on this information, I recommend that you take a look at our S385-25 channel balance. Please compare the dimensions of its attachments to your own. Does it look about right? I would also recommend the 2440 option, which can carry a window sash weight of 19 through 24 pounds. Double check to see if your sash's weight falls within that range.

Please keep in mind that the weight range 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.
