Well just checked my door and loosing some heat although I cant find where. So ordered the aluminum tonight. Seems 1 1/4 inch wide is all you need and 18 inches is long enough. didn't realize 1/8 inch aluminum got that high. Don't help you that you need to buy a 6 foot piece. So gong to have enough for maybe 4 repairs. LOL! So should get it by the weekend. So bottom repair coming up. Going to use Muebe idea but hope to reuse the original post.
