Integrated door closers are not visible from the outside and keep your doors closed. In normal operation as well as in case of fire. They are the solution when uninterrupted door optics are desired. This overhead door closer is completely embedded in the door leaf. Integrated door closers are ideally suited for high-quality doors within the context of sophisticated architecture. The guide rail is the only visible surface, and only when the door is open. They are also recommended for abuse prevention, for example in schools.
