Thanks for posting. You have an old Silverline Swinger window that uses a hinge balance system, where the balances in the window are not symmetrical. Both balances will use a 27" channel balance with 19-008 Top fitting. However, one of them will also have a 15-025 Bottom fitting attached. This balance will use a stamp option of 2620. For the opposite hinge side, you will need again a 27" channel balance but only the 19-008 Top attached. There will be no bottom fitting. The spring weight will be heavier, at 2630. These are not stock items, but we can easily make them for you via a custom order. I just sent you an email with a pair of purchase links to order one each. Let me know if you have further questions. |
