This is a 5-way which means that it restrains a person in five places: ankles, wrists, and, neck. Constructed of heavy wrought iron, chunky tow-chain, and, "Fetters"-type screw locks (using the same hex key). The locks are inline with the cuffs (I.e. parallel to the center line) providing a smoother look and feel. The profile of the metal constructing the cuffs is a "slice of a circle" - flat on the inside and rounded on the outside.
