Thanks for posting! I'm not 100% sure of what you have, but our 87-147 is designed for Superlite windows. Carefully compare our photos and dimensions to your existing roller to see if they match up. If not, we'll need you to remove the original roller assembly from the window in its entirety and upload some photos of it here for us to review. We can then try to find a better match. |
