Hi Jerry,

I think the “problem” in checking the contact reversal feature (auto-reverse) is a failure by HI’s to understand what that feature is supposed to do.

They fail or refuse to realize that the contact reversal pertains to entrapment issues and was never designed to prevent injury, only to prevent entrapment. Thus, they do stupid things like standing under the door and stop it half way down with their hands.

Here's some trivia for you. Circa 1950-1970, A-1 garage doors in Chicago (no longer around) made the 1-piece slab doors that would swing up and out, usually with giant springs on the sides that were vertical and pulled up from the floor...my dad made those doors. Of course there were others but if anyone has a a photo of one with the A-1 triangle logo on the front of the door, I'd love to see it.
