A shutter system and method in which the shutters are normally rolled to a nominal one foot width and have an infinite length, normally no less than two feet and no more than twelve feet is disclosed. These dimensions can be modified on one foot modules. The shutters are provided with a self-secured panel lock assembly at the overlapping joints on the inside between the shutter and windows normally on two foot spacing vertically. This can be horizontal, however, in other applications. The system includes the utilization of an angle frame at the base, and an overlapping receiver as a header. End caps may be of varying shapes but normally are typical L-shaped angles. The shutters are installed by raising the same upwardly and inwardly to the overhand on the upper header, lowering the same to the point where the lower portion overlap has a keyhole slot, aligning the same, and then manually threading the panel lock assembly in place and the bottom lock screw in place. Where the extrusions of the system are not employed, the threaded members engage a concrete anchor secured in the wall of the structure.
