23" Sash balance replacement needed

Hello,

We can supply your replacement balances but it will need to be a custom order. Before we get started, I would recommend double-checking the length of the metal channel, not including the end fittings. This type of assembly stamped with 23-4 would normally measure 24", which is why we want to be sure before moving forward. 

Also, please note that the minimum order would be two balances since it is important to replace both sides at the same to to ensure that the sash is equally supported. Thank you! 

Thanks for getting back to us. Since your stamp does not correspond with the length for this type of balance, we'll also need to confirm the exact weight of your window sash. That will help us ensure that the balance springs are calibrated to support the window properly.
