Abstract
An overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening in a wall, the door assembly having a flexible door panel and side columns located proximate opposite sides of the opening. The side columns each include an arm configured to engage the door panel as the door panel moves vertically, the arms being configured to move in a first direction in response to a first threshold moment being applied to the arms by the door panel wherein movement of each arm in the first direction prevents the door panel from escaping the side columns. The arms may be further configured to move in a second direction in response to a second threshold moment being applied on the arms by the door panel in a substantially vertical direction perpendicular to and away from the door panel.
