Abstract
A sectional door assembly, of the variety having a plurality of interconnected sections which are movable between a closed position and an open position. A flexible guide track is included on both sides of the door for guiding and supporting the plurality of sections between their respective open and closed positions. The flexible nature of the guide track, as well as the incorporation of a relatively quick release mechanism for retaining the guide track on the door's frame, allows for both minimization of damage to the door sections themselves and the time required to repair the door sections if they are accidentally damaged.
