Very durable, quality, thick insulation foam seal that stays put and looks great. It is definitely a 1-1/4" inch square piece and is 42" long. Very easy and quick to install around an ac unit that definitely keeps the hot air out and cold air in! Definitely consider using this--great value for the money!
