One popular style is the star anchor, an anchor plate in the shape of a star. Other names and styles of anchor plate include earthquake washer, triangular washer, S-iron, and T-head.

Anchor plates are made of cast iron, sometimes wrought iron or steel, and are often used on brick or other masonry-based buildings. They are easy to find in cities with substantial legacies of 18th- and 19th-century brick construction, such as Philadelphia, St. Louis, and Charleston, South Carolina, and in older earthquake prone cities such as San Francisco. The tie-rod-and-plate assembly serves to brace the masonry wall against lateral bowing.
