Hello, thank you for posting,

It appears that your channel balance uses the 19-009 top and 15-081 shoe attachments. We can assemble this balance configuration through a custom order. 

The length of the metal channel excluding the nylon attachments should measure 17" long, please confirm. 

Please provide the number of balances needed and I can send over an order link with pricing for your review. Note that custom orders have a minimum of (2) required. Thank you!
