Too thick for many doors. Sometimes 1 is not enough or even too much, sometimes 2 is too much but 1 is not enough. You're stuck too. So if you enter 2, it will jam even more. It would be nice if they made a flat one, about 1/32nd the thickness. I like how it's designed so you don't have to unscrew all the screws. For doors that looked good with just a seal, they were great and easy to use.
