I am trying to find a sill cap replacement for a steel in swing exterior door that is 36 inches wide. As you can see by the photos the aluminum threshhold has two vertical ridges that the cap snaps onto. The Cap removed is 1 1/2 inches wide and 1 1/4 high. Any help you can provide would be greatly appreciated as I have been looking all over to no avail and ordered twice from Home Depot but they were not the correct part. Thank you.
