Window Sash Balance
Hello! We can supply this balance, but it will have to be a custom order due to its configuration. What you have here is called an "extended travel" channel balance, named for its unique block and tackle system.
Thankfully, your photos tell us just about everything we need to get started. Can you just tell me how many you wanted to buy? Can you also verify the length of the metal channel? It should be 27-5/8".
Once I know that, I'll email you a purchase link and price quote that you can use to place an order on our site.
Perfect, thanks! I'll go ahead and email you that purchase link and price quote right now. Please let me know if you had any additional questions.
One last note: our balance is going to look a little different. Namely, it will have little tabs on the top and bottom plastic fittings. However despite this it will still function the same and you won't notice that difference once they're installed.
