TORRAMIUnder Door Draft Stoppers 30 Inch, Heavy Triangle Stop Draft Block Cold Air/Wind/Breeze Noise Blocker Door Sweeps Weather Stripping Bottom Seal Brown

Attractive, perfect size, and sticky tape helps it stay in place. I just got a new better door, but sill plan to use this to block cold air from slab adjacent to door frame. I bet I can add new Velcro to it and the bottom of the door.I have a second, equal diameter, but lighter weight for another door. This on beats it hands down, probably because it weighs more and because the Velcro strip keeps it in place.

We like to keep our entry door open in the winter to let light in so we purchased a 30" stopper for our storm door. We keep it laying there (didn't attach it to the storm door). It's well weighted so it stays put even when we open the storm door. (We just have to remember to step over it if we exit the house through that door.) Fits nicely between the two doors so we don't have to pick it up when we close our entry door at night.
