ABSTRACT:
An overhead door for occluding an opening in a structure. The door includes a pair of tracks having inwardly facing surfaces which define a channel. A door panel is located intermediate the pair of tracks and moveable along a predetermined path of travel which is defined by the tracks. A release assembly is borne by the door panel and is operable to releasably engage at least one of the tracks. The release assembly includes a moveable plunger which is received in the channel of one of the tracks and which guides the door panel along the path of travel. The plunger disengages from the channel when force of a predetermined magnitude is applied to the door panel.
