It amazes me every time I’m reminded of how small the world is (remember this?). Usually these encounters take the shape of connecting with someone I went to hardware school with in Savannah back in the late 80’s, or having students in my code class that I worked with 20 years ago. But I feel the same sense of “Wow! What a small world!” when two people send me a photo of the same door. 😀
Eric Maguire sent me some photos last week of 3-hour fire doors he saw at an art museum in Chicago. I immediately recognized them as doors that I wrote about back in 2009, when an architect sent me a photo so I could replicate the doors and hardware for Boston’s Museum of Fine Arts, which I was specifying at the time (here’s that photo!).
In my initial post about the doors, my point was that swing-clear hinges had been used, when pocket pivots would have been a better application. Although swing-clear hinges swing the door out of the opening like pocket pivots do, they also leave a +/- 2-inch gap between the frame face and the door edge, where pocket pivots leave almost no gap at all (here’s a post about pocket pivots, and the coordination of pocket depth).
This time, I would like to use these photos to point out (along with Eric), that wood wedges have been added to these fire door assemblies. These are 3-hour fire doors which divide the modern wing of the museum from the older wings. This is an award-winning museum which houses more than 300,000 works of art in its priceless collection. The chance of a fire may seem unlikely, but if a fire occurs, the wedged-open fire doors will not protect the rest of the museum. Smoke and flames will be allowed to spread freely through the open doors. I can’t help but wonder what their insurance company would say, or why all insurance companies are not requiring annual fire door inspections.
