I have used your 28" 770E balance for all my windows, but not for this size sash. I just ordered 4 of the 22" 770E, but cancelled when I looked at the markings- they are as follows in the single quotes: ' (2/90) UNIQUE 21-F 60' I measured it at 22". If I need custom, so be it, please advise. Thank you.

Thanks for posting! It looks like your balance may need to be custom made. Before we begin, though, I'd first like to confirm the weight of your sash. Based on your stamp, I want to recommend the custom option of 22F, which can support a sash weight range of 27 through 30 pounds. However, can you tell me if your window sash 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.

Thanks Tom. The sash weighs 35 pounds.

Oh, I see. In that case, you will need the 22H stamp, which can support 34 through 37 pounds. I've made up a Custom Channel Balance Order Form for you. Please fill out the Contact and Shipping information and one of our representatives will get in touch with you shortly thereafter.
