Rustic iron shutter dogs for decorative and functioning shutters. Also called a tie back, the iron sutter dog is a decorative piece that holds the shutter in place from the front side of the shutter. The term shutter dog is an Old English term stemming from the word "dog" meaning a fastener. Iron shutter dogs should be installed toward the outer edge of the shutter, they should be below or to the side of the shutter far enough to allow the shutter to swing past the tieback when it is turned to a nutral position. Many of our designs are shapped as a shutter s hook to create a symetrical look. All our iron shutter dogs are historical replicas and can be used on any style home.
