The high performance of contemporary closers can be appreciated by considering the limitations of primitive types incorporating a cord running from a door via a pulley to a counterweight mounted adjacent to the door frame. In addition to being used on doors with special needs, closer hinges are increasingly being employed on many types of ordinary doors due to economic, aesthetic, practical, and other reasons. Innovative engineering has made closer hinges more compact and functional the new generation of products provides unique combinations of features and benefits to address door closing challenges that are not satisfactorily met by overhead surface-mounted door closers.
