Hung these years ago when I built the house. Every window (10) and sliding glass door (10) around the exterior along with courtyard, breezeway, terrace and garage is shut and locked with a touch of a button. Today, these would cost 10X what they did in 1983... 😁

It's a nice feeling after all these years; especially at my age, now, that I don't have to spend a day and a half lugging panels while nailing and screwing them in place every time it blows.
