19-5 Milguard Balance
Hello there!
Thank you for reaching out to us. We can help supply this balance but it will have to be a custom order due to its configuration. The pulley wheel is built into the bottom fitting itself and this balance features an extended cord travel as well as a metal channel length ending in 5/8" which is what makes it custom. For example, the metal channel should measure 19-5/8" long. You can always measure yours to ensure it's the same.
I'll just need a few more details so that I can get this moving for you. Can you show us a photo of the top fitting as well as a side angle of the bottom fitting? Can you also confirm the number of balances you're looking to purchase?
