Abstract: A support assembly for doors, garage doors, or window shutters that cover building apertures. A support bar is mounted on a pivoting mount. Spring loaded locking assemblies are actuated by a lever assembly. With the locking assemblies retracted, the support can be pivoted from a horizontal passive position to a vertical engaged position. As the support assembly bar approaches the vertical position, the top lock assembly engages a top fixture and the bottom lock assembly engages a bottom fixture which are attached to the structure. External forces on the door or the shutter are transferred through the engaged support bar, through the fixtures, and to the building. The support bar mountably stays attached to the aperture cover, or door, in the passive position when the cover or door is opened.
