Thanks for posting. I recognize this balance, but it will have to be a custom order due to its configuration. I believe you need a 19" long metal channel with a 19-010 fitting installed at the top and 15-007 fitting installed at the bottom. Does that look good to you? We'd also go with an 1820 option for your 9 pound sash.
If that setup sounds good to you, please let me know how many you need. Once I know the quantity, I'll email you an order link and price quote for that many. This will allow you to place your order.
We do have dimensions on the 15-007 store page. I will also post them here for your convenience. Assuming everything matches up, I'll email you an order link and price quote right now for two balances according to the specifications I went over in my prior post.
We should have everything in stock, so delivery time will depend on the shipping option you select during checkout.
