I believe I can help. Most Alliance windows used our 26-243 and 26-244 top tilt latches. I believe your old pivot shoe could be our 15-175, which can use the S152-8 coil spring. You should go over our pictures and dimensions to confirm. Your covers are not available from the spring manufacturer, but they suggest the 15-150D for the bottom sash. The problem with the new cover is that the top tilt latches won't pass over it, so you will need to install it just below the closed position of the top tilt latch along the window channel. This will prevent the covers from interfering with tilt latch function. Let us know if you have further questions. |
