18 each - 9/16" x 25" (18lbs window)

Thanks for posting! Before I can offer an applicable replacement for these channel balances, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Hello Tom, The depth of mine are 1-3/32". Regards, Michae

Thanks for posting. In that case, I recommend checking our our Series 385 channel balance. Does that look about right?

For the 18 pound sash, I'd recommend the S385-25 with a 2430 stamp option. For the 22 pound sash, I'd recommend another S385-25, but this time with a 2440 stamp. Finally, for the 19 pound sash, I'd recommend the S385-20. However, there is no standard option for this balance that can support 19 pounds. It will have to be custom made.

Please take a look at this Custom Channel Balance Order Form that I have started for you and fill out the Contact and Billing information. One of our representatives will get in touch with you shortly thereafter.
