You see that you can see nothing at all: Integrated door closers are not visible from the outside, yet they keep your doors closed. If design, aesthetics and maximum safety are especially important for your door, choose a GEZE Boxer solution. This overhead door closer is completely embedded in the door leaf. The guide rail is the only surface visible, and only when the door is open. Integrated door closers are therefore ideally suited for high-quality doors within the context of sophisticated architecture.
