Hello, It looks like you have the old Silverline Swinger window. The 26" balance with the spring weight 2530 will have a 19-008 top and 15-025 bottom balance fitting attached. The opposite side 26" balance will have only the top fitting, 19-008 and the spring weight 2540. The 2540 balance with just the top goes on the hinge side track and the 2530 with both fittings go on the opposite side track. Please let us know if you have any other questions. Thank you! |
