East Pasadena's houses cluster tighter around 1951 than the rest of the service area does. Across the wider region, homes went up anywhere from 1943 to 2012 with a median around 1959 - but this pocket, sitting about 4 miles east of Pasadena proper, skews older than that median. A lot of these 2,036 households are sitting on garages that were framed for a shorter, narrower door opening than what gets manufactured today, with headroom that assumes a extension-spring setup rather than the torsion-on-a-shaft hardware that became standard later. If your garage still has the original frame, chances are it was never widened when the door itself got replaced somewhere down the line, which creates a mismatch between the opening and the hardware bolted to it. That's the thing to check first, not the door panel itself.
