The existing balances have a channel length of 26-1/4 inches and a channel width of 9/16 inches.
The number stamped on one of the balances is "4260-1-GJ Caldwell" The number stamped on the other balance for the same sash is "4260 2 H I".
The window sash weighs 21-1/2 pounds.
Can you please tell me which replacement balance I need for this window.
Thank you.
Doug
