The tiny screws for the end cap are almost impossible to screw in. I also worked for several hours to try and get the self tapping screws to work. I tried on my metal kitchen door and also on my wood living room door. They will not drill in even with a small pilot hole. I was excited to get it, and was going to order another one. I am returning this. I am very disappointed, it was waste of time and money.
