 Hi, I'm Jeff Moss and I'm a door hardware nerd. I am a shop technician for a very busy locksmith in Cleveland, Ohio, and I've been doing this professionally for about five and a half years. My door disclosure is recently I got to help install a set of rotons on some glass aluminum doors. It was only supposed to be one door where the pivot broke and when the technician showed up to fix it he discovered that a disgruntled patron had slammed the other door extremely hard Then we had to take both doors down and install continuous hinges on the whole opening
