I don't know, but I know what that wooden thing with the handle next to it is. It's an arm extension. When I was a little kid, my grandmother had one over both sides of every door of every room in her house, lying flat on those big old door trims that were 1" thick. This is how they worked when we were kids, all of us, the cousins too. Grandma was very, very, very old in her fifties, or at least it seemed to us when we were like four, five, six years old and stuff, and she was big and heavy, probably 150 pounds, which was enormous when we were four, five, six years old, and she couldn't run as fast as we could, but she didn't need to. Whenever we were bad and knew we were bad and it was time to run, we turned to run from her, but she always reached up to the top of a door jam trim, pulled down one of her trusty arm extenders, and WHACK, WHACK, WHACK like Zorro, problem solved, we lost every time. She could get five or six of us all within a second or two if we were close to each other, and close to any door in her house. We never won once ever.
You and your wife? Got those real tall old doors with huge old thick trim? Got one of them arm extenders over both sides of every door? I still got bumps on my head 50 years later. They work.
