The origin of the bean style dummy strap is not entirely clear, as decorative metalwork has been used in various forms throughout history and across many different cultures. However, the bean style dummy strap is commonly associated with traditional American architecture, particularly in the northeastern part of the United States.
During the 18th and 19th centuries, many homes and public buildings in this region were built using a style of architecture known as Federal or Georgian, which was characterized by its symmetrical design, use of brick or stone, and ornate decorative features. The bean style dummy strap was often used in conjunction with functional hinges to add a decorative element to doors and gates, and to create a sense of symmetry and balance in the overall design.
The term "bean style" refers to the shape of the decorative plate, which resembles a bean or kidney shape. This style of dummy strap was often made from wrought iron or other metals, and was typically handcrafted by skilled blacksmiths or metalworkers.
Today, the bean style dummy strap remains a popular decorative element in traditional American architecture, and can be found on many historic homes and public buildings throughout the northeastern United States.
