Window shutter hardware, usually made of iron, are hinges and latches that attach to the shutter and a window frame (and in some cases directly attached to stone or brick). The hinges hold the shutter to the structure and allow the shutter to open and close over the window. The latches secure the shutter in the closed (over the window) position. Tie-back hardware can be used to hold the shutter in the open position.
Exterior shutters were vital elements of homes in the colonies. Raised panel shutters provided security against access from ground level. Exterior shutters also proved a first barrier against the elements. In cities, shutters provided privacy screens for the residents.  Louvered upstairs shutters were often later additions to the home.
