I am trying to replace a 25" window channel balance. The old one is stamped with d 24-3. Which of your channel balance stamp options would be compatible to replace mine? Mine looks similiar to the series 37719-018 top 7 15-005 shoe.
Thanks, Steve

A stamp of 24-3 usually corresponds to our 2430 option. You can always also weigh your sash to be 100% sure what the best choice is.
