19 9 ?

Hello, thank you for posting,

We can supply your replacement balances but it will need to be a custom order due to the length, extended travel pulley system and unique combination of end attachments. 

The length of the metal channel excluding the nylon attachments should measure 19-5/8" long. Please confirm. 

How many balances are you in need of? For custom orders there is a minimum of (2). Once confirmed, I can send over an order link with pricing for your review. Thank you!
