I agree, the Series 751 looks like our closest match. The stamp option represents the strength of the channel balance. Locate the stamp on your channel balance. If your stamp does not match any of the stamp options available or you are unsure of which stamp option you should choose, please weigh your window sash and tell me the weight. We can then offer the best option.

Thank you. If the balance is stamped with 24, you may want to confirm the length by measuring the metal channel. All the stamps for the S751-24 begin with the number "23."
If the metal channel is 24" long, I recommend that you use the 23R stamp. Two balances with this stamp can carry a window sash weight of 10 through 18 pounds. However, if the metal channel is 25" long, you should use our S751-25 instead, this time with the 24R option. |
