shutter dog

An iron piece of hardware that projects from an exterior wall and has a head that swivels to lock a shutter in the open position; typically composed of a square plate fixed to the wall, a short, horizontal, projecting rod, and a forged tongue that swivels on the end of the rod, with the bottom of the tongue larger so that gravity holds it in a vertical position; the tongue may be of various shapes, including S-shaped and dart-shaped. Also known as turn, turn buckle. Photo from Williamsburg, Virginia, 2019. (Bucher, 1996)
