I don't want to sound like a moron, I know that Flexwatt is the stuff to use as far as heat tape goes. My question is, should I use the 3" wide or 11" wide? My rack that I'm building is going to be 48"T x24"D x36" W.... ? I was thinking just the 3" wide would do it, but just want to make sure I'm thinking right...(since that doesn't come about too often!)

LOL please help me out....
Thanks!
