With roughly 29,256 households in Glen Burnie, most sitting on doors installed in the mid-1970s, off-track calls cluster around the same handful of hardware types. Glen Burnie sits inside a climate band the federal data marks as severe cold, which means winter contraction on steel track brackets is a real factor here, not a guess. A bracket that's been through fifty winters of expansion and contraction loosens at the lag bolts, and a loose bracket lets the track drift a fraction of an inch - enough for a roller to walk off the rail on a cold morning when the steel's stiff and unforgiving.
Age plays into it too. Doors from this build era were hung on hardware sized for lighter panels than what's often installed today if a door's been swapped without upgrading the track to match. That mismatch is one of the more common off-track causes we see on calls out this way, more than storm damage or a single bad impact.
