Trammel heads are typically made of durable materials such as steel or brass, and they often have adjustable screws or knobs that allow for precise positioning and locking of the points. Some trammel heads may also have additional features, such as built-in rulers or protractors, to further enhance their functionality.

Overall, trammel heads are versatile and essential tools for craftsmen and artisans who need to accurately measure and mark out various shapes and distances in their work.
